Chemical Structure

Ethyl Methyl Sulfate CAS 814-40-4 chemical structure

Description

The occurrence of Ethyl Methyl Sulfate is closely related to a sulfone group, a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl Methyl Sulfate (CAS 814-40-4), molecular formula C3H8O4S and molecular weight 140.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl Methyl Sulfate (C3H8O4S) is characterized by a sulfone group, a carboxylic acid 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.

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.
