Chemical Structure

Ethyl Methyl Carbonate CAS 623-53-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 104.10 g/mol gives Ethyl Methyl Carbonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ethyl Methyl Carbonate (CAS 623-53-0), a certified reference material (molecular formula C4H8O3, MW 104.10 g/mol) for analytical method development and quality control.

Structurally, Ethyl Methyl Carbonate (C4H8O3) contains 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 104.10 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.
