Chemical Structure
Description
The occurrence of 2,2-Dimethyl-tetrahydrothiophene-3-carboxaldehyde is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,2-Dimethyl-tetrahydrothiophene-3-carboxaldehyde (CAS 83413-93-8), a certified reference material (molecular formula C7H12OS, MW 144.23 g/mol) for analytical method development and quality control.
Structurally, 2,2-Dimethyl-tetrahydrothiophene-3-carboxaldehyde (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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
