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.
[5-Methyl-2-(3-methylbutoxy)phenyl]boranediol (CAS 1313760-29-0), molecular formula C12H19BO3 and molecular weight 222.09 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H19BO3, [5-Methyl-2-(3-methylbutoxy)phenyl]boranediol contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 222.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
