Chemical Structure
Description
CATO supplies 5-Bromo-3-methyl-N-(3-pyridinylmethyl)-2-pyridinamine (CAS 1219976-57-4), a certified reference material (molecular formula C12H12BrN3, MW 278.15 g/mol) for analytical method development and quality control.
Structurally, 5-Bromo-3-methyl-N-(3-pyridinylmethyl)-2-pyridinamine (C12H12BrN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 278.15 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
