1-(4-(4-Methoxyphenyl)thiazol-2-yl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylic acid CAS 321848-16-2

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(4-(4-Methoxyphenyl)thiazol-2-yl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 369.32 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).

1-(4-(4-Methoxyphenyl)thiazol-2-yl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylic acid (CAS 321848-16-2), molecular formula C15H10F3N3O3S and molecular weight 369.32 g/mol, is a CATO reference standard with documented purity and traceability.

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.
