Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 141.10 g/mol gives 3-Fluoroisonicotinic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Fluoroisonicotinic acid (CAS 393-53-3), a certified reference material (molecular formula C6H4FNO2, MW 141.10 g/mol) for analytical method development and quality control.
Structurally, 3-Fluoroisonicotinic acid (C6H4FNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 141.10 g/mol, it falls into the low-molecular-weight range. 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.
CATO manufactures 3-Fluoroisonicotinic 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.
