2-(2,3,5-Trimethylphenoxy)ethane-1-sulfonyl chloride CAS 1018548-47-4

Description

The occurrence of 2-(2,3,5-Trimethylphenoxy)ethane-1-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.

2-(2,3,5-Trimethylphenoxy)ethane-1-sulfonyl chloride (CAS 1018548-47-4), molecular formula C11H15ClO3S and molecular weight 262.75 g/mol, is a CATO reference standard with documented purity and traceability.

2-(2,3,5-Trimethylphenoxy)ethane-1-sulfonyl chloride (C11H15ClO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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. 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), 2-(2,3,5-Trimethylphenoxy)ethane-1-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.
