Chemical Structure

4-(3,4-Dichlorophenoxy)benzenesulfonylchloride CAS 501697-77-4 chemical structure

Description

The occurrence of 4-(3,4-Dichlorophenoxy)benzenesulfonylchloride 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-(3,4-Dichlorophenoxy)benzenesulfonylchloride (CAS 501697-77-4) is a high-purity analytical reference standard with the molecular formula C12H7Cl3O3S and a molecular weight of 337.61 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 4-(3,4-Dichlorophenoxy)benzenesulfonylchloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 337.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 4-(3,4-Dichlorophenoxy)benzenesulfonylchloride 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.
