Chemical Structure

4-(Isopropylsulfonyl)phenol CAS 494794-53-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 200.25 g/mol gives 4-(Isopropylsulfonyl)phenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-(Isopropylsulfonyl)phenol (CAS 494794-53-5), a certified reference material (molecular formula C9H12O3S, MW 200.25 g/mol) for analytical method development and quality control.

Based on its molecular formula C9H12O3S, 4-(Isopropylsulfonyl)phenol 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).

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.
