Description
COA-BACKED NUTRITIONAL INGREDIENT
Pyridoxal-5-Phosphate Powder 98%
Pyridoxal-5-phosphate is supplied as a single-entity vitamin B6 derivative at 98.0% by HPLC, released against a batch-specific certificate of analysis. It is the phosphorylated, biologically active form of vitamin B6 and is a separate product from pyridoxine hydrochloride, which is dosed and declared differently. It is an industrial raw material for further processing and is not a finished consumer product.

Buyer Decision Guide
Agree the assay, the analytical method and the salt or hydrate form before approval. Confirm which vitamin B6 form the buyer’s finished-product specification and label call for, because the declaration differs between pyridoxine hydrochloride and pyridoxal-5-phosphate.
- Assay: 98.0% by HPLC, released against the batch COA.
- Vitamin B6 form confirmed: phosphorylated form, not pyridoxine hydrochloride.
- Light-protective packing and storage requirement stated.
- Particle size and packing agreed at quotation.
- COA, specification sheet and safety data sheet accompany each shipment.
- Regulatory status, permitted uses and labelling are the buyer’s responsibility for the destination market.
How This Grade Differs
Pyridoxal-5-phosphate and pyridoxine hydrochloride are different vitamin B6 forms sold under related names. They differ in molecular weight, in stability and in how they are declared on a finished-product label, so conversion between the two is not a simple weight substitution. Confirm the form the specification requires.
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
