Chemical Structure

2,4-Dimethylsulfolane CAS 1003-78-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2,4-Dimethylsulfolane (CAS 1003-78-7), molecular formula C6H12O2S and molecular weight 148.22 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,4-Dimethylsulfolane (C6H12O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 148.22 g/mol, it falls into the low-molecular-weight range.

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.
