CATO supplies 5-Oxo-1-tosyl-2,3,4,5-tetrahydro-1H-benzo[b]azepine-4-carbonitrile (CAS 68595-19-7), a certified reference material (molecular formula C18H16N2O3S, MW 340.40 g/mol) for analytical method development and quality control.
5-Oxo-1-tosyl-2,3,4,5-tetrahydro-1H-benzo[b]azepine-4-carbonitrile (C18H16N2O3S) contains a steroid core, 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.
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 5-Oxo-1-tosyl-2,3,4,5-tetrahydro-1H-benzo[b]azepine-4-carbonitrile 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.
