Chemical Structure

Ethyl 2-methyl-3-(p-tolylthio)propanoate CAS 1248295-96-6 chemical structure

Description

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.

CATO supplies Ethyl 2-methyl-3-(p-tolylthio)propanoate (CAS 1248295-96-6), a certified reference material (molecular formula C13H18O2S, MW 238.35 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 2-methyl-3-(p-tolylthio)propanoate (C13H18O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
