Chemical Structure
Description
The occurrence of 6-Chloro-4,5-dimethylpyridin-2-amine is closely related to a nitrile group, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Chloro-4,5-dimethylpyridin-2-amine (CAS 1083168-75-5), molecular formula C7H9ClN2 and molecular weight 156.61 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Chloro-4,5-dimethylpyridin-2-amine (C7H9ClN2) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. 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.
