n-(2-Bromo-4-methylphenyl)-4-chloropicolinamide CAS 923732-67-6

Description

The occurrence of n-(2-Bromo-4-methylphenyl)-4-chloropicolinamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies n-(2-Bromo-4-methylphenyl)-4-chloropicolinamide (CAS 923732-67-6), a certified reference material (molecular formula C13H10BrClN2O, MW 325.59 g/mol) for analytical method development and quality control.

Structurally, n-(2-Bromo-4-methylphenyl)-4-chloropicolinamide (C13H10BrClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 325.59 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
