Chemical Structure

2,5-Dibromo-4-methyl-3-nitropyridine CAS 947534-69-2 chemical structure

Description

The occurrence of 2,5-Dibromo-4-methyl-3-nitropyridine is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,5-Dibromo-4-methyl-3-nitropyridine (CAS 947534-69-2), a certified reference material (molecular formula C6H4Br2N2O2, MW 295.92 g/mol) for analytical method development and quality control.

2,5-Dibromo-4-methyl-3-nitropyridine (C6H4Br2N2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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

CATO manufactures 2,5-Dibromo-4-methyl-3-nitropyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
