Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Imidafenacin Impurity 5 HBr is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 377.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies Imidafenacin Impurity 5 HBr (CAS CATO-C4X-18085), a pharmacopoeial impurity reference standard (molecular formula C18H20N2O2HBr, MW 377.28 g/mol) used for the identification and quantification of trace impurities in APIs.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Imidafenacin Impurity 5 HBr 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.
