Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 275.05 g/mol gives 2-(Bromomethyl)-6-cyano-5-(difluoromethyl)pyridine-3-carboxaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(Bromomethyl)-6-cyano-5-(difluoromethyl)pyridine-3-carboxaldehyde (CAS 1805501-79-4) is a high-purity analytical reference standard with the molecular formula C9H5BrF2N2O and a molecular weight of 275.05 g/mol.
The molecular framework of 2-(Bromomethyl)-6-cyano-5-(difluoromethyl)pyridine-3-carboxaldehyde (C9H5BrF2N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
