Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, rac-Benzilonium Bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 434.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
rac-Benzilonium Bromide (CAS 1050-48-2), molecular formula C22H28NO3Br and molecular weight 434.37 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), rac-Benzilonium 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.
