9-chloro-2,3-diphenyl-7-(trifluoromethyl)pyrido[1,2-b][1,2,4]triazin-5-ium tetrafluoroborate CAS 249278-24-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 473.58 g/mol gives 9-chloro-2,3-diphenyl-7-(trifluoromethyl)pyrido[1,2-b][1,2,4]triazin-5-ium tetrafluoroborate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

9-chloro-2,3-diphenyl-7-(trifluoromethyl)pyrido[1,2-b][1,2,4]triazin-5-ium tetrafluoroborate (CAS 249278-24-8), molecular formula C20H12ClF3N3BF4 and molecular weight 473.58 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 9-chloro-2,3-diphenyl-7-(trifluoromethyl)pyrido[1,2-b][1,2,4]triazin-5-ium tetrafluoroborate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 473.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
