Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Potassium trifluoro(5-formylthiophen-3-yl)borate.
Potassium trifluoro(5-formylthiophen-3-yl)borate (CAS 907604-61-9) is a high-purity analytical reference standard with the molecular formula C5H3BF3OSK and a molecular weight of 218.04 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, Potassium trifluoro(5-formylthiophen-3-yl)borate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Potassium trifluoro(5-formylthiophen-3-yl)borate 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.
