2,4-Dichlorophenyl 4-phenyl-5-(trifluoromethyl)thiophene-2-carboxylate CAS 256348-21-7

Description

Compared with other compounds in its class, the molecular weight of 417.23 g/mol gives 2,4-Dichlorophenyl 4-phenyl-5-(trifluoromethyl)thiophene-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,4-Dichlorophenyl 4-phenyl-5-(trifluoromethyl)thiophene-2-carboxylate (CAS 256348-21-7), a certified reference material (molecular formula C18H9Cl2F3O2S, MW 417.23 g/mol) for analytical method development and quality control.

Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2,4-Dichlorophenyl 4-phenyl-5-(trifluoromethyl)thiophene-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 417.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2,4-Dichlorophenyl 4-phenyl-5-(trifluoromethyl)thiophene-2-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.
