Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(6-Fluoro-1H-pyrazin-2-ylidene)-hydrazine (CAS 1246471-20-4), molecular formula C4H5FN4 and molecular weight 128.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (6-Fluoro-1H-pyrazin-2-ylidene)-hydrazine (C4H5FN4) 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 (6-Fluoro-1H-pyrazin-2-ylidene)-hydrazine 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.
