Description
HIGH-PURITY SPECIALTY INGREDIENT
Melatonin Powder 99%
Melatonin is supplied as a single synthetic compound at 99.0% by HPLC, released against a batch-specific certificate of analysis. Because melatonin is regulated as a medicine or as a restricted ingredient in many markets, and the permitted position differs from country to country, the regulatory status of the destination market should be confirmed before the material is ordered. It is an industrial raw material and is not a finished consumer product.

Buyer Decision Guide
Agree the assay method and acceptance range, the impurity profile and the residual solvent limits applicable to the destination market before approval. Confirm the permitted-use position for melatonin in that market first: this determines whether the material can be used at all, and at what maximum level.
- Assay: 99.0% by HPLC, released against the batch COA.
- Permitted-use position in the destination market to be confirmed by the buyer.
- Impurity profile and residual solvents reported per batch.
- Physical form and particle size agreed against the buyer’s process.
- 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
Melatonin is quoted at several purities and in different physical forms. Assay, residual solvent profile and particle size all differ between grades, so a lower-purity material is not a drop-in replacement for a 99.0% grade. Compare quotations on the released assay and the impurity profile rather than the headline percentage.
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
