It's a white powder, 99%+ purity by HPLC, and the molecular weight sits at 663.43 g/mol — basically what you'd expect from a well-characterized NAD+ reference standdard for lab work.
Most buyers we work with are running metabolic or aging pathway studies, and they usually go through 5-10 grams per month. It's soluble in water, which makes it pretty straightforward for reconstitution, though you'll want to keep it at 2-8°C and dry and protected from light — we've seen degradation in about 20 days if left out.
The COA is availble on request for each batch, but we don't automatically include it unless you ask — just a heads-up. Lead time is typically 7-10 business days after payment clears, though for larger orders (50 grams or so) we may need to confirm stock first.
4, our company have an MOQ of 1 gram. Shippng is via cold pack if the weather's warm, though we don't cover that in base price — check with your logistics rep. It's not suited for any in vivo work without explicit institutional approval, so keep it strictly to the bench.
Also, we've had a few buyers ask if it's better than reagent grade NAD+ for their western blot controls, and the answer is yes — the tighter tolerance on purity (99%+ vs 98%) cuts down on background noise. Actually, we've seen this batch hold up well in long-term storage, but we don't have data past 24 months.
Payment terms are net 30 for approved accounts, otherwise it's upfront via wire or card. We usually have stock on the 99% powder, but confirm lead time if you need it next week — sometimes the HPLC verification takes an extra day.
