3-Bromo-2,8-bis(trifluoromethyl)-4H-pyrido[1,2-a]pyrimidin-4-one CAS 2648788-33-2 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 3-Bromo-2,8-bis(trifluoromethyl)-4H-pyrido[1,2-a]pyrimidin-4-one.

3-Bromo-2,8-bis(trifluoromethyl)-4H-pyrido[1,2-a]pyrimidin-4-one (CAS 2648788-33-2) is a high-purity analytical reference standard with the molecular formula C10H3BrF6N2O and a molecular weight of 361.04 g/mol.

3-Bromo-2,8-bis(trifluoromethyl)-4H-pyrido[1,2-a]pyrimidin-4-one (C10H3BrF6N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 3-Bromo-2,8-bis(trifluoromethyl)-4H-pyrido[1,2-a]pyrimidin-4-one 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.
