Chemical Structure
Description
CATO supplies 4-(Isopropylthio)phenol (CAS 70551-46-1), a certified reference material (molecular formula C9H12OS, MW 168.26 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H12OS, 4-(Isopropylthio)phenol contains sulfur-containing functionality, 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 168.26 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.
