We're looking at your NMN request and can confirm the CAS 1094-61-7 with a white crystalline powder, water soluble, and HPLC purity at 99% or better — the residual solvents are under 0.5% and heavy metals below 10ppm, which is tighter than reagent grade for most longevity studies.
The pH of a 1% solution runs 2.0-3.0, so if you're formulating for cellular uptake assays or NAD+ biosynthesis work, you'll want to buffer it — we've seen buyers use phosphate or Tris without issue, but the acidity is a real factor in some cell lines.
What it does is serve as a direct NAD+ precursor, shunting through the NMNAT pathway, and at this purity you're not dealing with the byproducts that can skew. Basically, teh enzymatic synthesis route gives you consistent batch-to-batch solubility.
Storage is 2-8°C for long term — we usually stock it, but confirm lead time if you need more than 50 kg. The shelf life is 24 months when kept dry and cold, though most labs burn through it faster anyway.
Also, this isn't suited for oral supplementation in humans — it's research use only, and the residual solvent spec (≤0.5%) is fine for in vitro but not GMP-grade for ingestibles. We include a COA with every batch, typically HPLC and TDS.
The 5 kg drum is easier to handle than the 25 kg pail, and MOQ is 1 kg if you're just starting a series. Anyway, our company can ship within 14 days or so once the PO clears.
