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 N-{1-[(4-methoxyphenyl)methyl]-5,6-dimethyl-1H-1,3-benzodiazol-4-yl}methanesulfonamide.
N-{1-[(4-methoxyphenyl)methyl]-5,6-dimethyl-1H-1,3-benzodiazol-4-yl}methanesulfonamide (CAS 338955-05-8) is a high-purity analytical reference standard with the molecular formula C18H21N3O3S and a molecular weight of 359.44 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-{1-[(4-methoxyphenyl)methyl]-5,6-dimethyl-1H-1,3-benzodiazol-4-yl}methanesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 359.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 N-{1-[(4-methoxyphenyl)methyl]-5,6-dimethyl-1H-1,3-benzodiazol-4-yl}methanesulfonamide 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.
