Description
As a certified reference material (CRM), 6-Fluoro-3-hydroxyquinoline-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.
6-Fluoro-3-hydroxyquinoline-4-carboxylic acid (CAS 1167056-89-4) is a high-purity analytical reference standard with the molecular formula C10H6FNO3 and a molecular weight of 207.16 g/mol.
Structurally, 6-Fluoro-3-hydroxyquinoline-4-carboxylic acid (C10H6FNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 207.16 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
