Chemical Structure
Description
The occurrence of 4-Amino-5-chloro-2-methylpyridine 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.
4-Amino-5-chloro-2-methylpyridine (CAS 97944-44-0), molecular formula C6H7ClN2 and molecular weight 142.59 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Amino-5-chloro-2-methylpyridine (C6H7ClN2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-Amino-5-chloro-2-methylpyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
