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.
(R)-1-(3-(Methylthio)phenyl)ethan-1-ol (CAS 2227839-14-5) is a high-purity analytical reference standard with the molecular formula C9H12OS and a molecular weight of 168.26 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, (R)-1-(3-(Methylthio)phenyl)ethan-1-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 168.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
