Description
HIGH-PURITY SPECIALTY INGREDIENT
Sialic acid (N-acetylneuraminic acid)
Sialic acid (N-acetylneuraminic acid) is supplied as a high-purity B2B raw material at 99.0%. This grade is produced to a declared purity with controlled identity, residual solvents and heavy metals, and is released against a batch-specific COA. It is intended for further processing by the buyer or for use as a reference material in development work; it is not a finished consumer product.

Buyer Decision Guide
Buyers approving Sialic acid (N-acetylneuraminic acid) normally agree four points before the first order: the assay method and acceptance range, the identity and isomeric form, the residual solvent limits applicable to the destination market, and the physical form required by the buyer’s process. Confirm these at enquiry stage so the shipment is released to the right specification.
- Assay: 99.0% by HPLC, released batch by batch against the current COA.
- Identity: confirmed by the analytical methods stated in the specification table above.
- Residual solvents and heavy metals: reported per batch and reviewed against the destination market’s limits.
- Physical form: powder as standard; packaging and particle size agreed against the buyer’s process.
- Documentation: COA, specification sheet and safety data sheet accompany each shipment.
- Regulatory status, permitted uses and labelling requirements are the buyer’s responsibility for the destination market.
How This Grade Differs
Sialic acid (N-acetylneuraminic acid) is often quoted alongside materials of the same or a closely related name at a different purity or in a different form. The two are not interchangeable: purity, residual solvent profile and physical form all change the buyer’s processing yield. Compare quotations on the released assay and the reported impurity profile, not on the headline percentage alone.

Frequently Asked Questions
Which test method should our QC lab expect to reproduce?
HPLC, with the reference standard and calculation basis recorded on the batch certificate.
What do you declare for moisture and ash?
Both are released against the limits on the approved specification; the measured result for your lot appears on its COA.
How is lot traceability handled?
Each lot keeps batch records and a retained sample, and the certificate for LXGZ260520 carries the same batch reference used in the quotation.
How does the material behave in your process?
It is supplied as Fine white crystalline powder at 98% through 80 mesh, so bulk density and flow are confirmed against your process before the first order.
How long can we hold stock before use?
Two years when stored properly from the manufacture date when the pack stays sealed and dry.
What is the minimum order quantity?
The regular MOQ is typically 1 kg. An evaluation sample of 10-20 g can usually be arranged before a formal order, subject to stock.
What packing options are available?
Standard packing is a sealed food-grade inner liner inside an export carton or fibre drum. Pack size, labelling and private-label artwork are agreed in the written specification.
Which documents come with the shipment?
Batch COA, specification sheet, agreed third-party testing where required, commercial invoice, packing list, certificate of origin and transport documents. The exact set is confirmed against the product and destination market.
