2-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)difluoromethyl)thiazole-4-carbonyl chloride CAS 1823183-05-6

Description

Structurally, 2-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)difluoromethyl)thiazole-4-carbonyl chloride (C11H3Cl2F5N2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 377.12 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

2-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)difluoromethyl)thiazole-4-carbonyl chloride (CAS 1823183-05-6) is a high-purity analytical reference standard with the molecular formula C11H3Cl2F5N2OS and a molecular weight of 377.12 g/mol.

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.
