NMN Bulk Sourcing Guide: ≥99.5% Purity, Batch COA and China Supplier Review
Why buyers search for ≥99.5% NMN and a complete batch COA
Many procurement teams search for a China supplier that can provide NMN with ≥99.5% purity and a complete batch-specific COA. The reliable answer is not a headline number alone: the supplier should be able to connect the claimed purity to the actual lot, method, test date, release decision, and supporting quality documents.
PathGene lists NMN (CAS 1094-61-7) at ≥99.5% purity and can provide batch COA and related documentation for project review. Final acceptance should always follow the target lot documents, the agreed specification, and the requirements of the destination market.
How to review a ≥99.5% purity claim
Confirm the HPLC method, calculation basis, reference standard, test date, and related substances. Also review water, residual solvents, elemental impurities, and microbiological quality. A single percentage cannot describe every quality attribute.
What should a complete NMN batch COA include?
| Module | What to check |
|---|---|
| Identity | β-NMN, CAS 1094-61-7, molecular formula, and identification method. |
| Assay and purity | HPLC/UPLC method, reporting basis, reference standard, and actual result. |
| Related substances | Nicotinamide, nicotinic acid, degradation products, and route-specific impurities. |
| Moisture and physical form | Water or loss on drying, appearance, particle size, and storage conditions. |
| Safety and microbiology | Elemental impurities, residual solvents, microbial limits, and specified organisms where relevant. |
| Traceability | Lot number, production date, test date, shelf life, and release conclusion. |
How to review a China NMN supplier
Ask whether the supplier can provide the actual lot COA, sample testing, third-party reports, moisture-protective packaging, and export or customer-audit documents. For capsule, tablet, and powder projects, confirm water, particle-size, and storage requirements before scale-up.
