(E)-3-(4-(Methylthio)phenyl)acrylic acid CAS 140134-65-2

Description

Compared with other compounds in its class, the molecular weight of 194.25 g/mol gives (E)-3-(4-(Methylthio)phenyl)acrylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E)-3-(4-(Methylthio)phenyl)acrylic acid (CAS 140134-65-2), molecular formula C10H10O2S and molecular weight 194.25 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (E)-3-(4-(Methylthio)phenyl)acrylic acid (C10H10O2S) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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

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.
