Chemical sequence

A chemical sequence is the catalog entity at Defiance International, a defined, ordered sequence supplied as a reference-grade material for in-vitro and laboratory research use only. Each listing carries its characterised identity, purity, and a batch Certificate of Analysis (COA). Chemical sequences are not drugs and are not intended for human use.

Certificate of Analysis (COA)

A Certificate of Analysis (COA) is the per-batch analytical record for a chemical sequence. It documents identity confirmation (typically HPLC / MS), measured purity, and the testing laboratory. Every batch we ship is traceable to its COA via the vial QR code, so the material in hand can be verified against its independently tested results.
