Chemical Structure

5-(tert-Butyl)benzo[b]thiophen-3(2H)-one CAS 79097-32-8 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-(tert-Butyl)benzo[b]thiophen-3(2H)-one (CAS 79097-32-8) is a high-purity analytical reference standard with the molecular formula C12H14OS and a molecular weight of 206.30 g/mol.

5-(tert-Butyl)benzo[b]thiophen-3(2H)-one (C12H14OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
