Chemical Structure
Description
3-((9H-Fluoren-2-yl)carbamoyl)picolinic acid (CAS 6341-20-4), molecular formula C22H36Cl5N2O3P and molecular weight 584.77 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C22H36Cl5N2O3P, 3-((9H-Fluoren-2-yl)carbamoyl)picolinic acid contains an amide group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 584.77 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures 3-((9H-Fluoren-2-yl)carbamoyl)picolinic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
