Chemical Structure

Ethyl 3-(m-tolyl)propiolate CAS 58686-70-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 188.22 g/mol gives Ethyl 3-(m-tolyl)propiolate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ethyl 3-(m-tolyl)propiolate (CAS 58686-70-7), a certified reference material (molecular formula C12H12O2, MW 188.22 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H12O2, Ethyl 3-(m-tolyl)propiolate contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 188.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures Ethyl 3-(m-tolyl)propiolate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
