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.

4-((3R,3'S,3a'S,6a'R)-3'-Benzyl-6-chloro-7-methyl-2,4',6'-trioxo-2',3',3a',4',6',6a'-hexahydro-5'H-spiro[indoline-3,1'-pyrrolo[3,4-c]pyrrol]-5'-yl)phenyl acetate (CAS 956249-37-9), molecular formula C29H24ClN3O5 and molecular weight 529.97 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C29H24ClN3O5, 4-((3R,3'S,3a'S,6a'R)-3'-Benzyl-6-chloro-7-methyl-2,4',6'-trioxo-2',3',3a',4',6',6a'-hexahydro-5'H-spiro[indoline-3,1'-pyrrolo[3,4-c]pyrrol]-5'-yl)phenyl acetate contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 529.97 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO manufactures 4-((3R,3'S,3a'S,6a'R)-3'-Benzyl-6-chloro-7-methyl-2,4',6'-trioxo-2',3',3a',4',6',6a'-hexahydro-5'H-spiro[indoline-3,1'-pyrrolo[3,4-c]pyrrol]-5'-yl)phenyl acetate 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.
