Chemical Structure
Description
As a certified reference material (CRM), 5-chloropyridazin-4-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
5-chloropyridazin-4-amine (CAS 53180-92-0), molecular formula C4H10ClN3 and molecular weight 135.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-chloropyridazin-4-amine (C4H10ClN3) is characterized by chlorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
