N-(5-bromo-4-methylpyridin-2-yl)methanesulfonamide CAS 779331-64-5

Description

The occurrence of N-(5-bromo-4-methylpyridin-2-yl)methanesulfonamide is closely related to an amide group, a sulfone 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.

N-(5-bromo-4-methylpyridin-2-yl)methanesulfonamide (CAS 779331-64-5), molecular formula C7H9BrN2O2S and molecular weight 265.13 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, N-(5-bromo-4-methylpyridin-2-yl)methanesulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 265.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
