Chemical Structure

2-Methyl-2-phenylpropane-1-sulfonyl chloride CAS 125125-33-9 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 2-Methyl-2-phenylpropane-1-sulfonyl chloride.

2-Methyl-2-phenylpropane-1-sulfonyl chloride (CAS 125125-33-9), molecular formula C10H13ClO2S and molecular weight 232.73 g/mol, is a CATO reference standard with documented purity and traceability.

2-Methyl-2-phenylpropane-1-sulfonyl chloride (C10H13ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
