Chemical Structure
Description
The occurrence of 4-Chloro-N-(2-((4-chlorobenzylidene)amino)-1,2-bis(4-chlorophenyl)ethyl)benzamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Chloro-N-(2-((4-chlorobenzylidene)amino)-1,2-bis(4-chlorophenyl)ethyl)benzamide (CAS 115294-32-1), molecular formula C28H20Cl4N2O and molecular weight 542.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Chloro-N-(2-((4-chlorobenzylidene)amino)-1,2-bis(4-chlorophenyl)ethyl)benzamide (C28H20Cl4N2O) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Chloro-N-(2-((4-chlorobenzylidene)amino)-1,2-bis(4-chlorophenyl)ethyl)benzamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
