Chemical Structure

3-Chloro-2,6-dinitropyridine CAS 101079-67-8 chemical structure

Description

The occurrence of 3-Chloro-2,6-dinitropyridine is closely related to a carbohydrate-derived structure, an amide group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Chloro-2,6-dinitropyridine (CAS 101079-67-8), molecular formula C5H2ClN3O4 and molecular weight 203.54 g/mol, is a CATO reference standard with documented purity and traceability.

3-Chloro-2,6-dinitropyridine (C5H2ClN3O4) contains a carbohydrate-derived structure, an amide group, 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), 3-Chloro-2,6-dinitropyridine 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.
