Chemical Structure

1-(4-Chlorophenyl)propane-2-sulfonyl chloride CAS 1017338-18-9 chemical structure

Description

The occurrence of 1-(4-Chlorophenyl)propane-2-sulfonyl chloride 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.

1-(4-Chlorophenyl)propane-2-sulfonyl chloride (CAS 1017338-18-9) is a high-purity analytical reference standard with the molecular formula C9H10Cl2O2S and a molecular weight of 253.15 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 1-(4-Chlorophenyl)propane-2-sulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.15 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.

As a certified reference material (CRM), 1-(4-Chlorophenyl)propane-2-sulfonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
