A researcher running a dose-response curve for a specific metabolic pathway study needs something they can trust vial to vial — what it does is eliminate the guesswork when your assay depends on tight tolerance between batches, and we've had clients come back saying the 5mg vials reconstituted exactly as expected with no precipitation issues.
Purity is tested via HPLC with a COA issued for every batch, and we keep the raw data on file for about two years if you ever need to dig into the specifics — the 99% figure is consistent across teh last 12 we've tracked, but the real value is the batch-to-batch variability which typically stays under 0.3% base on internal QC logs.
We usually have stock in the 10-vial kits (the 10mg size is what most buyers go with), but the 15mg vials are a special order that takes 20 days or so to clear — also, the retest policy is straightforward: if your in-house HPLC flags anything below 98.5% within 30 days of receipt, we replace at no cost, no questions asked.
Storage is pretty much standerd — cool, dry, away form light — but what I've noticed from handling these is that the powder stays stable for about 9 months at room temp, though the COA guarantees only 6 months from ship date (check lead time on your order because we're seeing 4-6 weeks for internatioanl destinations right now).
This isn't suited for anything in solution preparation beyond research protocols, so don't let anyone try to repurpose it for workup steps — CAS 303760-60-3 matches the hydrazide structure, and the white powder appearance matches what you'd expect for this grade, though we don't test for residual solvents beyond basic limits.
Yes, we test each batch with HPLC to confirm 99% purity minimum, and we can provide the certificate of analysis with your order.
You can order individual vials in 5mg, 10mg, or 15mg sizes — no need to buy the full kit. The kit is just an option if you want a bulk pack.
We ship within 24-48 hours after payment confirmation, and global delivery usually takes 5-10 business days depending on your location.
Absolutely — we include a COA with every order showing purity results, and we can also supply an MSDS upon request.
Keep them in a cool, dry place away from direct light. Avoid moisture and high temperatures to maintain stability.
