Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-Methyl-3-(4,4,5,5-tetraMethyl-1,3,2-dioxaborolan-2-yl)phenyl)Methanol.
(4-Methyl-3-(4,4,5,5-tetraMethyl-1,3,2-dioxaborolan-2-yl)phenyl)Methanol (CAS 1400755-04-5), molecular formula C14H21BO3 and molecular weight 248.13 g/mol, is a CATO reference standard with documented purity and traceability.
(4-Methyl-3-(4,4,5,5-tetraMethyl-1,3,2-dioxaborolan-2-yl)phenyl)Methanol (C14H21BO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
