Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
2-(3-Cyclopropyl-4-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2223031-05-6), molecular formula C16H23BO2 and molecular weight 258.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3-Cyclopropyl-4-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C16H23BO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
