2-Chloro-3-nitro-6-phenylpyridine CAS 187242-88-2

Description

Compared with other compounds in its class, the molecular weight of 234.64 g/mol gives 2-Chloro-3-nitro-6-phenylpyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-3-nitro-6-phenylpyridine (CAS 187242-88-2), molecular formula C11H7ClN2O2 and molecular weight 234.64 g/mol, is a CATO reference standard with documented purity and traceability.

2-Chloro-3-nitro-6-phenylpyridine (C11H7ClN2O2) 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, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

As a certified reference material (CRM), 2-Chloro-3-nitro-6-phenylpyridine 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.
