Chemical Structure
Description
5-Chloro-2-hydrazinyl-3-nitropyridine (CAS 22353-46-4), molecular formula C5H5ClN4O2 and molecular weight 188.57 g/mol, is a CATO reference standard with documented purity and traceability.
5-Chloro-2-hydrazinyl-3-nitropyridine (C5H5ClN4O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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 5-Chloro-2-hydrazinyl-3-nitropyridine 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.
