7-benzyl-2-[4-(trifluoromethyl)phenyl]-3H,4H,5H,6H,7H,8H-pyrido[3,4-d]pyrimidin-4-one hydrochloride CAS 1803603-84-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 425.88 g/mol gives 7-benzyl-2-[4-(trifluoromethyl)phenyl]-3H,4H,5H,6H,7H,8H-pyrido[3,4-d]pyrimidin-4-one hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 7-benzyl-2-[4-(trifluoromethyl)phenyl]-3H,4H,5H,6H,7H,8H-pyrido[3,4-d]pyrimidin-4-one hydrochloride (CAS 1803603-84-0), a certified reference material (molecular formula C21H22F3N3OHCl, MW 425.88 g/mol) for analytical method development and quality control.

The molecular framework of 7-benzyl-2-[4-(trifluoromethyl)phenyl]-3H,4H,5H,6H,7H,8H-pyrido[3,4-d]pyrimidin-4-one hydrochloride (C21H22F3N3OHCl) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 7-benzyl-2-[4-(trifluoromethyl)phenyl]-3H,4H,5H,6H,7H,8H-pyrido[3,4-d]pyrimidin-4-one hydrochloride 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.
