Chemical Structure
Description
The molecular framework of 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (3-cyclopentylfuran-2-yl)boronate (C15H25BO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (3-cyclopentylfuran-2-yl)boronate (CAS 2223042-57-5), molecular formula C15H25BO4 and molecular weight 280.17 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
