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.
CATO supplies 2,3-Dihydro-1-benzothiophen-3-ol (CAS 17347-03-4), a certified reference material (molecular formula C8H8OS, MW 152.21 g/mol) for analytical method development and quality control.
2,3-Dihydro-1-benzothiophen-3-ol (C8H8OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
