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-Methoxy-3-methyl-N-(thiophen-2-ylmethyl)benzenesulfonamide.
CATO supplies 4-Methoxy-3-methyl-N-(thiophen-2-ylmethyl)benzenesulfonamide (CAS 873580-57-5), a certified reference material (molecular formula C13H15NO3S2, MW 297.39 g/mol) for analytical method development and quality control.
4-Methoxy-3-methyl-N-(thiophen-2-ylmethyl)benzenesulfonamide (C13H15NO3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
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-Methoxy-3-methyl-N-(thiophen-2-ylmethyl)benzenesulfonamide 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.
