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 Diazene, 1,2-bis[4-(4-bromobutoxy)phenyl]-.
Diazene, 1,2-bis[4-(4-bromobutoxy)phenyl]- (CAS 222046-22-2), molecular formula C20H24Br2N2O2 and molecular weight 484.22 g/mol, is a CATO reference standard with documented purity and traceability.
Diazene, 1,2-bis[4-(4-bromobutoxy)phenyl]- (C20H24Br2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Diazene, 1,2-bis[4-(4-bromobutoxy)phenyl]- 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.
