Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Potassium 3,5-dimethylisoxazole-4-yltrifluoroborate.
Potassium 3,5-dimethylisoxazole-4-yltrifluoroborate (CAS 1111732-84-3) is a high-purity analytical reference standard with the molecular formula C5H6BF3NOK and a molecular weight of 203.01 g/mol.
The molecular framework of Potassium 3,5-dimethylisoxazole-4-yltrifluoroborate (C5H6BF3NOK) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 3,5-dimethylisoxazole-4-yltrifluoroborate 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.
