The occurrence of Ethyl 2-(2-chloro-4-(chlorosulfonyl)phenoxy)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.
CATO supplies Ethyl 2-(2-chloro-4-(chlorosulfonyl)phenoxy)acetate (CAS 4547-67-5), a certified reference material (molecular formula C10H10Cl2O5S, MW 313.15 g/mol) for analytical method development and quality control.
Ethyl 2-(2-chloro-4-(chlorosulfonyl)phenoxy)acetate (C10H10Cl2O5S) 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, 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Ethyl 2-(2-chloro-4-(chlorosulfonyl)phenoxy)acetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
