Chemical Structure

1-(sec-Butyl)-3-((4-chlorophenyl)sulfonyl)-2-imino-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one CAS 607383-14-2 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 1-(sec-Butyl)-3-((4-chlorophenyl)sulfonyl)-2-imino-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one (CAS 607383-14-2), a certified reference material (molecular formula C21H19ClN4O3S, MW 442.92 g/mol) for analytical method development and quality control.

1-(sec-Butyl)-3-((4-chlorophenyl)sulfonyl)-2-imino-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one (C21H19ClN4O3S) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures 1-(sec-Butyl)-3-((4-chlorophenyl)sulfonyl)-2-imino-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one 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.
