Chemical Structure
Description
CATO supplies N2-Ethylpyridine-2,5-diamine dihydrochloride (CAS 1439897-72-9), a certified reference material (molecular formula C7H11N3HCl, MW 173.64 g/mol) for analytical method development and quality control.
N2-Ethylpyridine-2,5-diamine dihydrochloride (C7H11N3HCl) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures N2-Ethylpyridine-2,5-diamine dihydrochloride 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.
