Chemical Structure
Description
The occurrence of Ethyl 4-(4-chlorophenyl)-6-[(4-chlorophenyl)sulfanyl]-5-formyl-2-methyl-1,4-dihydropyridine-3-carboxylate is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 4-(4-chlorophenyl)-6-[(4-chlorophenyl)sulfanyl]-5-formyl-2-methyl-1,4-dihydropyridine-3-carboxylate (CAS 339100-97-9) is a high-purity analytical reference standard with the molecular formula C22H19Cl2NO3S and a molecular weight of 448.36 g/mol.
The molecular framework of Ethyl 4-(4-chlorophenyl)-6-[(4-chlorophenyl)sulfanyl]-5-formyl-2-methyl-1,4-dihydropyridine-3-carboxylate (C22H19Cl2NO3S) is characterized by a steroid core, an amide group, a sulfone 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), Ethyl 4-(4-chlorophenyl)-6-[(4-chlorophenyl)sulfanyl]-5-formyl-2-methyl-1,4-dihydropyridine-3-carboxylate 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.
