Description

CATO manufactures 4'-(4-Chloro-3-nitrophenyl)-1'-methyldispiro[chromane-3,3'-pyrrolidine-2',3''-indoline]-2'',4-dione 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.

4'-(4-Chloro-3-nitrophenyl)-1'-methyldispiro[chromane-3,3'-pyrrolidine-2',3''-indoline]-2'',4-dione (CAS 1177601-98-7), molecular formula C26H20ClN3O5 and molecular weight 489.91 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4'-(4-Chloro-3-nitrophenyl)-1'-methyldispiro[chromane-3,3'-pyrrolidine-2',3''-indoline]-2'',4-dione (C26H20ClN3O5) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
