Description
As a certified reference material (CRM), Potassium 5-formylthiophene-2-trifluoroborate 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.
Potassium 5-formylthiophene-2-trifluoroborate (CAS 1025113-78-3) is a high-purity analytical reference standard with the molecular formula C5H3BF3OSK and a molecular weight of 218.04 g/mol.
Potassium 5-formylthiophene-2-trifluoroborate (C5H3BF3OSK) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
