7-(4-Fluorophenyl)-2-((3,4,4-trifluorobut-3-en-1-yl)thio)-[1,2,4]triazolo[1,5-a]pyrimidine CAS 478043-72-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-(4-Fluorophenyl)-2-((3,4,4-trifluorobut-3-en-1-yl)thio)-[1,2,4]triazolo[1,5-a]pyrimidine.

7-(4-Fluorophenyl)-2-((3,4,4-trifluorobut-3-en-1-yl)thio)-[1,2,4]triazolo[1,5-a]pyrimidine (CAS 478043-72-0) is a high-purity analytical reference standard with the molecular formula C15H10F4N4S and a molecular weight of 354.33 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution, 7-(4-Fluorophenyl)-2-((3,4,4-trifluorobut-3-en-1-yl)thio)-[1,2,4]triazolo[1,5-a]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 354.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
