Chemical Structure
Description
CATO supplies 3-chloro-5-fluoropyridine-4-carboxylic acid (CAS 514798-03-9), a certified reference material (molecular formula C6H9ClFNO2, MW 181.59 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H9ClFNO2, 3-chloro-5-fluoropyridine-4-carboxylic acid contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 181.59 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-5-fluoropyridine-4-carboxylic acid 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.
