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 2-Phenyl-1-(p-tolyl)-1,5,6,7,8,9-hexahydroimidazo[1,2-a]azepin-4-ium bromide.
2-Phenyl-1-(p-tolyl)-1,5,6,7,8,9-hexahydroimidazo[1,2-a]azepin-4-ium bromide (CAS 301525-94-0), molecular formula C21H23N2Br and molecular weight 383.33 g/mol, is a CATO reference standard with documented purity and traceability.
2-Phenyl-1-(p-tolyl)-1,5,6,7,8,9-hexahydroimidazo[1,2-a]azepin-4-ium bromide (C21H23N2Br) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 2-Phenyl-1-(p-tolyl)-1,5,6,7,8,9-hexahydroimidazo[1,2-a]azepin-4-ium bromide 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.
