Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-tert-Butyl-3-[(2-methylphenyl)methyl]-2,3,4,5-tetrahydro-1H-1,3,4-benzotriazepine-2,5-dione.
4-tert-Butyl-3-[(2-methylphenyl)methyl]-2,3,4,5-tetrahydro-1H-1,3,4-benzotriazepine-2,5-dione (CAS 866157-54-2), molecular formula C20H23N3O2 and molecular weight 337.42 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-tert-Butyl-3-[(2-methylphenyl)methyl]-2,3,4,5-tetrahydro-1H-1,3,4-benzotriazepine-2,5-dione (C20H23N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 337.42 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).
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), 4-tert-Butyl-3-[(2-methylphenyl)methyl]-2,3,4,5-tetrahydro-1H-1,3,4-benzotriazepine-2,5-dione 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.
