About the compound & documentation

Factual notes on the compound and the product as supplied: chemical identity, storage, and certification. Questions about specific research applications are out of scope.

01What is H₂O + BA | H (Bacteriostatic Water)?
H₂O + BA | H is Bacteriostatic Water, a research-grade compound supplied for laboratory research use only. It is not for human or veterinary use, and is not for any diagnostic or therapeutic purpose. Lot-specific purity and analytical results are reported on the certificate of analysis for the batch received.
02How is the product stored before shipping?
Vials are held at −20 °C in a desiccated, dark environment and dispatched the same business day the order is placed.
03What does the COA include?
Reverse-phase HPLC purity (220 nm), ESI(+) mass spectrum with delta calculation, LAL endotoxin per USP <85>, water content by Karl Fischer titration, residual TFA, residual solvents per ICH Q3C, heavy metals by ICP-MS, and a signed release statement.
04What is the difference between the lot number and the COA number?
The lot ID (B-…) identifies the synthesis batch. The COA ID (COA-…) identifies the specific certificate issued for that lot. Both are printed on the vial label and the shipment paperwork.
05Where can I find prior lot COAs?
All historical COAs for every lot are kept in the COA Archive (linked in the header). Lots are listed by SKU and date; the archive contains the full PDF for every release.
