Chemical Structure
Description
The occurrence of Potassium Methoxymethyltrifluoroborate is closely related to a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Potassium Methoxymethyltrifluoroborate (CAS 910251-11-5), molecular formula C2H5BF3OK and molecular weight 151.96 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, Potassium Methoxymethyltrifluoroborate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 151.96 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 Methoxymethyltrifluoroborate 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.
