Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Leupeptin Ac-LL (hydrochloride).
CATO supplies Leupeptin Ac-LL (hydrochloride) (CAS 24125-16-4), a certified reference material (molecular formula C20H38N6O4HCl, MW 463.02 g/mol) for analytical method development and quality control.
Structurally, Leupeptin Ac-LL (hydrochloride) (C20H38N6O4HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 463.02 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Leupeptin Ac-LL (hydrochloride) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
