Chemical Structure
Description
The occurrence of 5-(3-Methoxycarbonylphenyl)-picolinic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(3-Methoxycarbonylphenyl)-picolinic acid (CAS 1242339-64-5), molecular formula C14H11NO4 and molecular weight 257.24 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H11NO4, 5-(3-Methoxycarbonylphenyl)-picolinic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 257.24 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5-(3-Methoxycarbonylphenyl)-picolinic 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.
