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.
5-(4-Butoxyphenyl)-1-(3,4-dimethylphenyl)-3-((3,4-dimethylphenyl)amino)-1,5-dihydro-2H-pyrrol-2-one (CAS 312517-94-5), molecular formula C30H34N2O2 and molecular weight 454.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(4-Butoxyphenyl)-1-(3,4-dimethylphenyl)-3-((3,4-dimethylphenyl)amino)-1,5-dihydro-2H-pyrrol-2-one (C30H34N2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 5-(4-Butoxyphenyl)-1-(3,4-dimethylphenyl)-3-((3,4-dimethylphenyl)amino)-1,5-dihydro-2H-pyrrol-2-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.
