Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including n-(2-Amino-4-methylphenyl)methanesulfonamide.
n-(2-Amino-4-methylphenyl)methanesulfonamide (CAS 71173-42-7) is a high-purity analytical reference standard with the molecular formula C8H12N2O2S and a molecular weight of 200.26 g/mol.
n-(2-Amino-4-methylphenyl)methanesulfonamide (C8H12N2O2S) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
