Product Overview
ChemSP supplies potassium 4-nitrophenyl sulphate to formulators, traders and research groups that need a documented, repeatable lot rather than an ad-hoc sample.
Its formula C6H4KNO6S corresponds to 6 carbon atoms, 4 hydrogen atoms, 1 potassium atom, 1 nitrogen atom, 6 oxygen atoms and 1 sulfur atom; that fixed ratio is what makes lot-to-lot equivalence testable rather than a matter of judgement.
At 257.26 it is a small molecule in the usual fine-chemical range, handled much like other solid or liquid intermediates of similar size.

| Molecular Formula | C6H4KNO6S |
| Molecular Weight | 257.26 |
| Catalog Category | Inorganic Chemicals |
Composition and Key Properties
The formula points to a nitrogen- and oxygen-bearing framework (amide, amino acid or hydroxamate type), sulfur-containing functionality together with a mineral (metal-bearing) salt form — worth confirming against structural data before an analytical method is validated. A comparatively low hydrogen-to-carbon ratio together with the ring count is consistent with an aromatic or otherwise highly unsaturated core.
Applications and Use Cases
potassium 4-nitrophenyl sulphate (CAS 6217-68-1, molecular formula C6H4KNO6S, molecular weight 257.26 g/mol) is mainly applied in chemical synthesis, fine chemical manufacturing and related industrial processes. For specification, COA and bulk prices of potassium 4-nitrophenyl sulphate, write to our sales team.
- Use as a mineral source or counter-ion where the hydrated form drives the effective dose.
- pH adjustment, precipitation or catalyst-support work in aqueous systems.
- Blending into formulations where the anion, not just the assay, sets performance.
Specific end-uses should be checked against your own regulatory assessment before the material is qualified in a finished product.
Packaging and Handling
Supplied in standard export packaging appropriate to the physical form of the material. The exact pack size, inner liner and net weight are fixed on the order acknowledgement, since they depend on whether the lot ships as a solid, a paste or a liquid. Customers with drum, liner or pallet constraints should specify them when enquiring.
Quality and Documentation
Every lot is released against a written specification and ships with its own COA; the SDS follows the current GHS revision. Where a customer needs an additional test — heavy metals, residual solvent, particle size — it can normally be added to the specification for future lots.
Supply and Quotation
Quotations are issued against the product name and CAS number, with quantity, destination port or address, and any specification adjustments stated in the enquiry. Normal reply time is one business day.
Frequently Asked Questions
What is the CAS number of potassium 4-nitrophenyl sulphate?
The CAS registry number for potassium 4-nitrophenyl sulphate is 6217-68-1. Please quote it on any enquiry so that a quotation is matched to the correct grade.
Is potassium 4-nitrophenyl sulphate a stock item or made to order?
Availability moves with the production schedule, so it is confirmed at the time of enquiry. For repeat volumes a scheduled call-off arrangement is usually preferable to one-off orders.
Can you supply potassium 4-nitrophenyl sulphate with a specification we define?
Yes. The acceptance criteria can be adjusted within what the route allows — most often assay, moisture, heavy metals or particle size. Any change is written into the specification before the lot is released.

Extended Specifications
potassium 4-nitrophenyl sulphate is supplied against a clear, batch-specific specification. When you request a quote, our team confirms the assay or purity grade, physical form, pack size and any residue limits relevant to your application. Typical parameters documented on the Certificate of Analysis include identity (CAS number), molecular formula, molecular weight, appearance, assay, loss on drying and heavy-metal limits where applicable.
Applications by Industry
Buyers source potassium 4-nitrophenyl sulphate across food and beverage, nutraceutical and pharmaceutical, cosmetic and personal care, and selected industrial formulations. ChemSP aligns the grade and documentation set to the target application and destination market.
Regulatory & Compliance Support
ChemSP ships potassium 4-nitrophenyl sulphate with a Certificate of Analysis for every batch and a Safety Data Sheet on request. Additional documentation such as specification sheets, third-party test reports and regulatory support letters is available to qualified buyers to streamline import, registration and quality-assurance workflows.
Storage & Handling
Store potassium 4-nitrophenyl sulphate in a cool, dry, well-ventilated area in its original, tightly closed container, protected from moisture and direct sunlight. Follow the precautions in the Safety Data Sheet and standard chemical-handling guidance. Shelf life and re-test intervals are stated on the Certificate of Analysis.
Frequently Asked Questions
What is the minimum order quantity (MOQ)?
MOQ depends on grade and pack size. Sampling quantities typically start from 1 kg, with commercial volumes from 25 kg. Share your required volume and we will quote accordingly.
Can I request a sample and a Certificate of Analysis?
Yes. Samples and batch-specific Certificates of Analysis are available on request, and third-party testing can be arranged for qualified buyers.
What documentation supports import and registration?
Every shipment includes a Certificate of Analysis. The Safety Data Sheet, specification sheets and regulatory support letters are provided on request to support customs clearance and product registration in your market.
What are the typical lead times and payment terms?
Lead times vary with grade and volume. ChemSP quotes a firm delivery window with each offer, and standard international trading terms apply.

The table below is calculated from the molecular formula C6H4KNO6S. The values are theoretical and are intended as a reference for incoming inspection and for setting a purchase specification.
Contains the metallic element K. The material behaves as an inorganic salt: it is non-volatile, generally water-soluble, and leaves an inorganic residue on ignition.
Contains nitrogen (1 atoms). Nitrogen-bearing structures are often amine-like: they can absorb carbon dioxide from air and develop odour if the packaging is not tight.
Contains sulfur. Sulfur-bearing materials may darken or develop odour under heat and should be kept away from oxidising agents.
A degree of unsaturation of 6 points to an aromatic or ring-containing skeleton.
At 257.26 g/mol the molar mass is in the small-molecule range, where volatility and dust generation are the practical handling concerns.
Identity and Registry Data
- CAS number
- 6217-68-1
Handling, Storage and Stability
Store sealed in a dry, well-ventilated area. Inorganic salts take up moisture readily and may cake or partially dissolve; keep away from strong acids.
Protect from light and air. Unsaturated and aromatic structures tend to darken on oxidation, so opaque or inert-headspace packaging is preferred for long storage.
Store under ventilation with tightly closed packaging; amine-type nitrogen absorbs carbon dioxide from air and may develop odour.
Typical Specification Parameters
- Assay / content
- Loss on drying / moisture
- Appearance and odour
- Heavy metals (as Pb)
- Shelf life and packaging
- Residue on ignition (sulfated ash)
These are the parameters normally reported on a certificate of analysis. Limits are lot-specific and follow the specification agreed between supplier and buyer; no numeric limits are stated or implied here.
