Chemical Structure
Description
Lithium triisopropyl 2-(5-chloropyridyl)borate (C14H24BClNO3Li) contains a salt form, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Lithium triisopropyl 2-(5-chloropyridyl)borate (CAS 1256364-35-8) is a high-purity analytical reference standard with the molecular formula C14H24BClNO3Li and a molecular weight of 307.55 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Lithium triisopropyl 2-(5-chloropyridyl)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.
