Chemical Structure
Description
Sodium 6-chloro-[1,2,4]triazolo[4,3-b]pyridazine-3-carboxylate (CAS 1630906-50-1) is a high-purity analytical reference standard with the molecular formula C6H2ClN4O2Na and a molecular weight of 220.55 g/mol.
The molecular framework of Sodium 6-chloro-[1,2,4]triazolo[4,3-b]pyridazine-3-carboxylate (C6H2ClN4O2Na) is characterized by a salt form, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
