Ethyl 2-methylbenzenesulfonate CAS 59222-96-7

Description

Compared with other compounds in its class, the molecular weight of 200.25 g/mol gives Ethyl 2-methylbenzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 2-methylbenzenesulfonate (CAS 59222-96-7), molecular formula C9H12O3S and molecular weight 200.25 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H12O3S, Ethyl 2-methylbenzenesulfonate contains a sulfone group, 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 200.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 2-methylbenzenesulfonate 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.
