When we're looking at replacing a suplier mid-cycle because the last batch had inconsistent particle size and the HPLC showed 97.2% instead of the claimed 99%, the first thing I checked was their retest policy — they'll reissue a COA at 6 months, which is better than typical 3-month window most vendors offer, and that alone saves us form having to reorder prematurely.
CAS 98-92-0, white powder with a stated purity of ≥99% by HPLC, and they include a full COA with each shipment that covers residual solvents and heavy metals down to single-digit ppm levels — we usually have stock, but confirm lead time is 10 business days or so for quantities over 25 kg, and the MOQ is 1 kg which is reasonable for a validation run.
For someone running long-term stability studies where batch-to-batch consistency matters more than absolute purity, this is a solid choice, but it's actually not ideal if you're working with cell-based assays that require sterile filtration right out of teh bag because the powder can contain endotoxins at levels that vary by lot — we've seen 0.5 to 2.0 EU/mg on some COAs, so plan accordingly.
Anyway, the GMP and ISO 9001 certs are current, the HS code is 2936240000, and the price per gram drops significantly at the 10 kg mark, so I ordered 5 kg to start while we run our own internal HPLC verification.
Our MOQ for NMN powder is typically 1 kilogram, but we can discuss smaller quantities for first-time orders or research samples.
Lead time is usually 7–15 business days after order confirmation, depending on your location and shipping method.
Yes, we can include GMP, HSE, and ISO 9001 certificates along with the batch-specific analysis report for your order.
Store it in a cool, dry place away from direct sunlight and moisture—ideally below 25°C in a sealed container to keep it stable.
We offer custom packaging and labeling for bulk orders, like private labeling or specific bag sizes—just let us know your requirements.
