Chemical Structure
Description
(4-Butylphenyl)(5-methylthiophen-2-yl)methanol (CAS 944697-64-7), molecular formula C16H20OS and molecular weight 260.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-Butylphenyl)(5-methylthiophen-2-yl)methanol (C16H20OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
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.
