4,5-Dichloro-3-(2-ethoxyethoxy)thiophene-2-carboxylic acid CAS 1708251-09-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,5-Dichloro-3-(2-ethoxyethoxy)thiophene-2-carboxylic acid.

CATO supplies 4,5-Dichloro-3-(2-ethoxyethoxy)thiophene-2-carboxylic acid (CAS 1708251-09-5), a certified reference material (molecular formula C9H10Cl2O4S, MW 285.14 g/mol) for analytical method development and quality control.

4,5-Dichloro-3-(2-ethoxyethoxy)thiophene-2-carboxylic acid (C9H10Cl2O4S) 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 4,5-Dichloro-3-(2-ethoxyethoxy)thiophene-2-carboxylic acid 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.
