Description
Compared with other compounds in its class, the molecular weight of 198.57 g/mol gives 4-Amino-6-chloro-3-nitropicolinonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Amino-6-chloro-3-nitropicolinonitrile (CAS 944388-71-0), a certified reference material (molecular formula C6H3ClN4O2, MW 198.57 g/mol) for analytical method development and quality control.
4-Amino-6-chloro-3-nitropicolinonitrile (C6H3ClN4O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 4-Amino-6-chloro-3-nitropicolinonitrile 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.
