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 4-Amino-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfonamide sulfate (CAS 24540-76-9), a certified reference material (molecular formula C12H14N4O2SH2O4S, MW 376.40 g/mol) for analytical method development and quality control.
4-Amino-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfonamide sulfate (C12H14N4O2SH2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 4-Amino-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfonamide sulfate 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.
