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 4-(2-Bromobenzyl)-1-(phenylsulfonyl)piperidine-4-carboxylic acid.
4-(2-Bromobenzyl)-1-(phenylsulfonyl)piperidine-4-carboxylic acid (CAS 1171661-56-5) is a high-purity analytical reference standard with the molecular formula C19H20BrNO4S and a molecular weight of 438.34 g/mol.
4-(2-Bromobenzyl)-1-(phenylsulfonyl)piperidine-4-carboxylic acid (C19H20BrNO4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, 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.
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.
CATO manufactures 4-(2-Bromobenzyl)-1-(phenylsulfonyl)piperidine-4-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
