Chemical Structure

2,4-Dibromo-5-(difluoromethyl)-3-nitropyridine CAS 1806786-16-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4-Dibromo-5-(difluoromethyl)-3-nitropyridine.

2,4-Dibromo-5-(difluoromethyl)-3-nitropyridine (CAS 1806786-16-2), molecular formula C6H2Br2F2N2O2 and molecular weight 331.90 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H2Br2F2N2O2, 2,4-Dibromo-5-(difluoromethyl)-3-nitropyridine contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 331.90 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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