Chemical Structure
Description
CATO supplies 2,3-Dimethyl 6-chloropyridine-2,3-dicarboxylate (CAS 32383-03-2), a certified reference material (molecular formula C9H8ClNO4, MW 229.62 g/mol) for analytical method development and quality control.
2,3-Dimethyl 6-chloropyridine-2,3-dicarboxylate (C9H8ClNO4) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
As a certified reference material (CRM), 2,3-Dimethyl 6-chloropyridine-2,3-dicarboxylate 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.
