Chemical Structure
Description
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 supplies (2s)-2-(4-Chlorobenzenesulfonamido)-3-(1h-indol-3-yl)propanoic acid (CAS 85979-01-7), a certified reference material (molecular formula C17H15ClN2O4S, MW 378.83 g/mol) for analytical method development and quality control.
(2s)-2-(4-Chlorobenzenesulfonamido)-3-(1h-indol-3-yl)propanoic acid (C17H15ClN2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures (2s)-2-(4-Chlorobenzenesulfonamido)-3-(1h-indol-3-yl)propanoic 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.
