Chemical Structure
Description
The molecular framework of 2-chloro-1,3-bis(3,4-dimethylphenyl)propane-1,3-dione (C19H19ClO2) is characterized by a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-chloro-1,3-bis(3,4-dimethylphenyl)propane-1,3-dione (CAS 937602-14-7) is a high-purity analytical reference standard with the molecular formula C19H19ClO2 and a molecular weight of 314.81 g/mol.
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 2-chloro-1,3-bis(3,4-dimethylphenyl)propane-1,3-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.
