Chemical Structure

(2,2-Dimethyl-2,5-dihydrothiophen-3-yl)methanol CAS 83413-88-1 chemical structure

Description

(2,2-Dimethyl-2,5-dihydrothiophen-3-yl)methanol (CAS 83413-88-1) is a high-purity analytical reference standard with the molecular formula C7H12OS and a molecular weight of 144.23 g/mol.

Structurally, (2,2-Dimethyl-2,5-dihydrothiophen-3-yl)methanol (C7H12OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 144.23 g/mol, it falls into the low-molecular-weight range.

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.
