Chemical Structure

2-(Difluoromethyl)-3-fluoro-4-nitropyridine-6-carbonyl chloride CAS 1806009-74-4 chemical structure

Description

The occurrence of 2-(Difluoromethyl)-3-fluoro-4-nitropyridine-6-carbonyl chloride is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-(Difluoromethyl)-3-fluoro-4-nitropyridine-6-carbonyl chloride (CAS 1806009-74-4), a certified reference material (molecular formula C7H2ClF3N2O3, MW 254.55 g/mol) for analytical method development and quality control.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 2-(Difluoromethyl)-3-fluoro-4-nitropyridine-6-carbonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 254.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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

As a certified reference material (CRM), 2-(Difluoromethyl)-3-fluoro-4-nitropyridine-6-carbonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
