Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(Benzenesulfonyl)-3-[(4-chlorophenyl)sulfanyl]propan-2-ol.
1-(Benzenesulfonyl)-3-[(4-chlorophenyl)sulfanyl]propan-2-ol (CAS 338409-57-7) is a high-purity analytical reference standard with the molecular formula C15H15ClO3S2 and a molecular weight of 342.86 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 1-(Benzenesulfonyl)-3-[(4-chlorophenyl)sulfanyl]propan-2-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
