Product Overview
Pigment Yellow 109 is offered by ChemSP (Jinan Shenghe Chemical Co., Ltd.) as a catalogued dyes & pigments raw material for B2B buyers.
Written as C23H8Cl8N4O2, the molecule contains 23 carbon atoms, 8 hydrogen atoms, 8 chlorine atoms, 4 nitrogen atoms and 2 oxygen atoms in a single defined ratio — the basis for assay calculation and for reconciling batch weights against a specification.
At 655.9 it is a mid-sized molecule, typically supplied as a free-flowing solid or a viscous liquid depending on the salt form.
Chemical Identity
| CAS Number | 5045-40-9 |
|---|---|
| Molecular Formula | C23H8Cl8N4O2 |
| Molecular Weight | 655.9 |
| LogP (calculated) | 8.6 |
| Catalog Category | Dyes & Pigments |
Composition and Key Properties
The formula points to a nitrogen- and oxygen-bearing framework (amide, amino acid or hydroxamate type) together with a halogenated framework — 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.
LogP 8.6 makes it highly lipophilic, so emulsion or surfactant-assisted handling is usually worth evaluating early.
Applications and Use Cases
Pigment Yellow 109 (CAS 5045-40-9; formula C23H8Cl8N4O2; 655.9 g/mol) is used in chemical synthesis, fine chemical manufacturing and related industrial processes. Contact our sales team for the specification, COA and bulk pricing of Pigment Yellow 109.
- Used in paints
- Inks
- Plastics
- And as catalysts
These are uses on record, not a claim of suitability for any particular process. Whether the material fits a given application depends on the specification you set and on the regulations of the destination market.
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 Pigment Yellow 109?
The CAS registry number for Pigment Yellow 109 is 5045-40-9. Please quote it on any enquiry so that a quotation is matched to the correct grade.
Can you supply Pigment Yellow 109 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.
Which documents come with the shipment?
A batch-specific COA and a GHS-format safety data sheet. Additional declarations — non-GMO, allergen, origin, or a customer-specific template — can be issued on request.

Extended Specifications
Pigment Yellow 109 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 Pigment Yellow 109 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 Pigment Yellow 109 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 Pigment Yellow 109 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 C23H8Cl8N4O2. The values are theoretical and are intended as a reference for incoming inspection and for setting a purchase specification.
Contains the halogen Cl. Halogenated structures can release acidic vapour on heating or hydrolysis, so contact with bare metal surfaces should be controlled.
Contains nitrogen (4 atoms). Nitrogen-bearing structures are often amine-like: they can absorb carbon dioxide from air and develop odour if the packaging is not tight.
A degree of unsaturation of 18 points to an aromatic or ring-containing skeleton.
Identity and Registry Data
- CAS number
- 5045-40-9
Handling, Storage and Stability
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.
Keep in corrosion-resistant, tightly closed containers. Halogenated material may release acidic vapour when heated or hydrolysed.
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
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.
