(3R,4S,5S,7aR)-3,5,6,7a-Tetramethyl-1-oxo-N,N-diphenyl-1,3,3a,4,5,7a-hexahydroisobenzofuran-4-carboxamide CAS 2459955-54-3 chemical structure

Description

CATO supplies (3R,4S,5S,7aR)-3,5,6,7a-Tetramethyl-1-oxo-N,N-diphenyl-1,3,3a,4,5,7a-hexahydroisobenzofuran-4-carboxamide (CAS 2459955-54-3), a certified reference material (molecular formula C25H27NO3, MW 389.49 g/mol) for analytical method development and quality control.

(3R,4S,5S,7aR)-3,5,6,7a-Tetramethyl-1-oxo-N,N-diphenyl-1,3,3a,4,5,7a-hexahydroisobenzofuran-4-carboxamide (C25H27NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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 (3R,4S,5S,7aR)-3,5,6,7a-Tetramethyl-1-oxo-N,N-diphenyl-1,3,3a,4,5,7a-hexahydroisobenzofuran-4-carboxamide 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.
