Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 158.56 g/mol gives Picolinoyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Picolinoyl chloride (CAS 29745-44-6), molecular formula C6H5NO2Cl and molecular weight 158.56 g/mol, is a CATO reference standard with documented purity and traceability.
Picolinoyl chloride (C6H5NO2Cl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
As a certified reference material (CRM), Picolinoyl chloride 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.
