Description
CATO manufactures 3-[(4-Chlorophenyl)methyl]-1-[(4-methylphenyl)methanesulfonyl]-3-(pyrazin-2-yl)urea 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.
CATO supplies 3-[(4-Chlorophenyl)methyl]-1-[(4-methylphenyl)methanesulfonyl]-3-(pyrazin-2-yl)urea (CAS 866150-91-6), a certified reference material (molecular formula C20H19ClN4O3S, MW 430.91 g/mol) for analytical method development and quality control.
3-[(4-Chlorophenyl)methyl]-1-[(4-methylphenyl)methanesulfonyl]-3-(pyrazin-2-yl)urea (C20H19ClN4O3S) contains a steroid 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
