Chemical Structure

4-Chloro-5-nitro-2-(trifluoromethyl)pyridine CAS 438554-45-1 chemical structure

Description

Based on its molecular formula C6H2ClF3N2O2, 4-Chloro-5-nitro-2-(trifluoromethyl)pyridine contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 226.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies 4-Chloro-5-nitro-2-(trifluoromethyl)pyridine (CAS 438554-45-1), a certified reference material (molecular formula C6H2ClF3N2O2, MW 226.54 g/mol) for analytical method development and quality control.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
