2-Ethynyl-4-methylthiophene CAS 859795-08-7 chemical structure

Description

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.

2-Ethynyl-4-methylthiophene (CAS 859795-08-7) is a high-purity analytical reference standard with the molecular formula C7H6S and a molecular weight of 122.19 g/mol.

2-Ethynyl-4-methylthiophene (C7H6S) contains sulfur-containing functionality, 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).

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.
