ChemSP — A brand of Jinan Shenghe Chemical Co., Ltd.
High-quality Zinc methionine supplied by ChemSP Competitive pricing, reliable delivery, and full technical support for B2B buyers worldwide.
ChemSP - your B2B chemical sourcing brand. We provide consolidated logistics and multilingual technical support to ensure every shipment is stable and reliable.
ChemSP supplies Zinc methionine to formulators, traders and research groups that need a documented, repeatable lot rather than an ad-hoc sample.
Its formula C10H20N2O4S2Zn corresponds to 10 carbon atoms, 20 hydrogen atoms, 2 nitrogen atoms, 4 oxygen atoms, 2 sulfur atoms and 1 zinc atom; that fixed ratio is what makes lot-to-lot equivalence testable rather than a matter of judgement.
At 361.8 it is a mid-sized molecule, typically supplied as a free-flowing solid or a viscous liquid depending on the salt form.

| Molecular Weight | 361.8 |
| Catalog Category | Feed Additives / Food Additives |
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.
Zinc methionine (CAS 40816-51-1, molecular formula C10H20N2O4S2Zn, molecular weight 361.8 g/mol) is mainly applied in chemical synthesis, fine chemical manufacturing and related industrial processes. For specification, COA and bulk prices of Zinc methionine, write to our sales team.
Specific end-uses should be checked against your own regulatory assessment before the material is qualified in a finished product.
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.
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.
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.
What is the CAS number of Zinc methionine?
The CAS registry number for Zinc methionine is 40816-51-1. Please quote it on any enquiry so that a quotation is matched to the correct grade.
Is Zinc methionine 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 Zinc methionine 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.
Zinc methionine 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.
Buyers source Zinc methionine 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.
ChemSP ships Zinc methionine 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.
Store Zinc methionine 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.
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.
Yes. Samples and batch-specific Certificates of Analysis are available on request, and third-party testing can be arranged for qualified buyers.
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.
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 C10H20N2O4S2Zn. The values are theoretical and are intended as a reference for incoming inspection and for setting a purchase specification.
Contains the metallic element Zn. The material behaves as an inorganic salt: it is non-volatile, generally water-soluble, and leaves an inorganic residue on ignition.
Contains nitrogen (2 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.
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.
Store under ventilation with tightly closed packaging; amine-type nitrogen absorbs carbon dioxide from air and may develop odour.
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.
Zinc methionine is identified by CAS 40816-51-1, molecular formula C10H20N2O4S2Zn and a molar mass of 361.8 g/mol.
Calculated from C10H20N2O4S2Zn, the composition by mass is: C 33.2%, Zn 18.1%, S 17.7%, O 17.7%, N 7.7%, H 5.6%.
A certificate of analysis normally reports Assay / content, Loss on drying / moisture, Appearance and odour, Heavy metals (as Pb), Shelf life and packaging, Residue on ignition (sulfated ash). Exact limits are agreed with the buyer and are lot-specific.
Store in a cool, dry, well-ventilated place away from heat, direct sunlight and incompatible materials. Keep container tightly closed. Use appropriate personal protective equipment and refer to the SDS for full safety guidance before handling.
Yes. A batch-specific COA and free or charged sample are available on request before bulk ordering.
Yes. We offer custom grade, particle size and purity adjustment based on your application and order volume.
MOQ depends on the product; small quantities are supported for R&D and trial runs.
Every batch is tested in-house and retains full traceability from raw material to finished goods.
