Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Z-Gly-Gly-Phe-chloromethylketone (CAS 35172-59-9), molecular formula C22H24ClN3O5 and molecular weight 445.90 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Z-Gly-Gly-Phe-chloromethylketone (C22H24ClN3O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 445.90 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), Z-Gly-Gly-Phe-chloromethylketone 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.
