Description

Compared with other compounds in its class, the molecular weight of 358.26 g/mol gives (3E,5E)-3,5-Bis[(3-chlorophenyl)methylidene]-1-methylpiperidin-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(3E,5E)-3,5-Bis[(3-chlorophenyl)methylidene]-1-methylpiperidin-4-one (CAS 54237-29-5), molecular formula C20H17Cl2NO and molecular weight 358.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (3E,5E)-3,5-Bis[(3-chlorophenyl)methylidene]-1-methylpiperidin-4-one (C20H17Cl2NO) 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 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).

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 (3E,5E)-3,5-Bis[(3-chlorophenyl)methylidene]-1-methylpiperidin-4-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.
