Ethyl 6-amino-1-(4-chlorophenyl)-5-cyano-4-(2,4-dichlorophenyl)-2-methyl-1,4-dihydropyridine-3-carboxylate CAS 692287-67-5

Description

CATO supplies Ethyl 6-amino-1-(4-chlorophenyl)-5-cyano-4-(2,4-dichlorophenyl)-2-methyl-1,4-dihydropyridine-3-carboxylate (CAS 692287-67-5), a certified reference material (molecular formula C22H18Cl3N3O2, MW 462.76 g/mol) for analytical method development and quality control.

Ethyl 6-amino-1-(4-chlorophenyl)-5-cyano-4-(2,4-dichlorophenyl)-2-methyl-1,4-dihydropyridine-3-carboxylate (C22H18Cl3N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), Ethyl 6-amino-1-(4-chlorophenyl)-5-cyano-4-(2,4-dichlorophenyl)-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.
