188781-15-9 Ethyl-2-trifluoromethyl-4-trifluoromethyl-5-pyrimidine carboxylate ethyl 2,4-bis(trifluoromethyl)pyrimidine-5-carboxylate CAS 188781-15-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 188781-15-9 Ethyl-2-trifluoromethyl-4-trifluoromethyl-5-pyrimidine carboxylate ethyl 2,4-bis(trifluoromethyl)pyrimidine-5-carboxylate.

CATO supplies 188781-15-9 Ethyl-2-trifluoromethyl-4-trifluoromethyl-5-pyrimidine carboxylate ethyl 2,4-bis(trifluoromethyl)pyrimidine-5-carboxylate (CAS 188781-15-9), a certified reference material (molecular formula C9H6F6N2O2, MW 288.15 g/mol) for analytical method development and quality control.

The molecular framework of 188781-15-9 Ethyl-2-trifluoromethyl-4-trifluoromethyl-5-pyrimidine carboxylate ethyl 2,4-bis(trifluoromethyl)pyrimidine-5-carboxylate (C9H6F6N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
