Chemical Structure

4-Amino-3,5-difluoropyridine CAS 159783-22-9 chemical structure

Description

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.

4-Amino-3,5-difluoropyridine (CAS 159783-22-9), molecular formula C5H4F2N2 and molecular weight 130.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Amino-3,5-difluoropyridine (C5H4F2N2) is characterized by a nitrile group, fluorine substitution. 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.

CATO manufactures 4-Amino-3,5-difluoropyridine 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.
