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.
2-Phenyl-2-{[4-(propan-2-yl)phenyl]sulfanyl}acetic acid (CAS 938287-63-9) is a high-purity analytical reference standard with the molecular formula C17H18O2S and a molecular weight of 286.39 g/mol.
Structurally, 2-Phenyl-2-{[4-(propan-2-yl)phenyl]sulfanyl}acetic acid (C17H18O2S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 286.39 g/mol, it falls into the medium-molecular-weight range. 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.
