Cyclohexene-1-boronic acid pinacol ester CAS 141091-37-4

Description

The occurrence of Cyclohexene-1-boronic acid pinacol ester is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Cyclohexene-1-boronic acid pinacol ester (CAS 141091-37-4), molecular formula C12H21BO2 and molecular weight 208.10 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Cyclohexene-1-boronic acid pinacol ester (C12H21BO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 208.10 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.

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.

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.
