2-(3-Bromo-4-(difluoromethoxy)benzoyl)pyridine CAS 1261671-91-3

Description

Compared with other compounds in its class, the molecular weight of 328.11 g/mol gives 2-(3-Bromo-4-(difluoromethoxy)benzoyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(3-Bromo-4-(difluoromethoxy)benzoyl)pyridine (CAS 1261671-91-3) is a high-purity analytical reference standard with the molecular formula C13H8BrF2NO2 and a molecular weight of 328.11 g/mol.

2-(3-Bromo-4-(difluoromethoxy)benzoyl)pyridine (C13H8BrF2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

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.
