Chemical Structure

4-(4-Methoxyphenyl)-2-[3-methyl-5-(trifluoromethyl)-1H-pyrazol-1-yl]-1,3-thiazole CAS 955976-85-9 chemical structure

Description

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.

4-(4-Methoxyphenyl)-2-[3-methyl-5-(trifluoromethyl)-1H-pyrazol-1-yl]-1,3-thiazole (CAS 955976-85-9) is a high-purity analytical reference standard with the molecular formula C15H12F3N3OS and a molecular weight of 339.34 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 4-(4-Methoxyphenyl)-2-[3-methyl-5-(trifluoromethyl)-1H-pyrazol-1-yl]-1,3-thiazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.34 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).

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.
