11-(3,5-Dibromo-4-hydroxyphenyl)-3,3,8-trimethyl-2,3,4,5,10,11-hexahydro-1H-dibenzo[b,e][1,4]diazepin-1-one (CAS 1024232-75-4), molecular formula C22H22Br2N2O2 and molecular weight 506.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 11-(3,5-Dibromo-4-hydroxyphenyl)-3,3,8-trimethyl-2,3,4,5,10,11-hexahydro-1H-dibenzo[b,e][1,4]diazepin-1-one (C22H22Br2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine 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 506.23 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 11-(3,5-Dibromo-4-hydroxyphenyl)-3,3,8-trimethyl-2,3,4,5,10,11-hexahydro-1H-dibenzo[b,e][1,4]diazepin-1-one 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.
