Chemical Structure
Description
The occurrence of Potassium (2-chloropyridin-3-yl)trifluoroborate is closely related to a salt form, a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Potassium (2-chloropyridin-3-yl)trifluoroborate (CAS 1201899-19-5), molecular formula C5H3BClF3NK and molecular weight 219.44 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, a nitrile group, fluorine/chlorine substitution, Potassium (2-chloropyridin-3-yl)trifluoroborate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 219.44 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 (2-chloropyridin-3-yl)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.
