Chemical Structure
Description
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.
2-(2-(Cyclohexylmethoxy)-6-methoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1204580-87-9), molecular formula C20H31BO4 and molecular weight 346.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(2-(Cyclohexylmethoxy)-6-methoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C20H31BO4) is characterized by a steroid core, 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.
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.
