4-(Chlorosulfonyl)phenyl acetate CAS 79119-26-9

Description

The occurrence of 4-(Chlorosulfonyl)phenyl acetate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(Chlorosulfonyl)phenyl acetate (CAS 79119-26-9), molecular formula C8H7ClO4S and molecular weight 234.66 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H7ClO4S, 4-(Chlorosulfonyl)phenyl acetate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 234.66 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
