Chemical Structure

Ethyl Methyl Sulfoxide CAS 1669-98-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl Methyl Sulfoxide.

Ethyl Methyl Sulfoxide (CAS 1669-98-3) is a high-purity analytical reference standard with the molecular formula C3H8OS and a molecular weight of 92.16 g/mol.

The molecular framework of Ethyl Methyl Sulfoxide (C3H8OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
