Chemical Structure
Description
Structurally, 2-(Isochroman-7-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C15H21BO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 260.14 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 2-(Isochroman-7-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1643572-75-1), a certified reference material (molecular formula C15H21BO3, MW 260.14 g/mol) for analytical method development and quality control.
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.
