Chemical Structure
Description
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.
2-(2,5-Dichlorobenzoyl)-5-(1,3-dioxolan-2-yl)thiophene (CAS 898778-90-0) is a high-purity analytical reference standard with the molecular formula C14H10Cl2O3S and a molecular weight of 329.20 g/mol.
2-(2,5-Dichlorobenzoyl)-5-(1,3-dioxolan-2-yl)thiophene (C14H10Cl2O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 2-(2,5-Dichlorobenzoyl)-5-(1,3-dioxolan-2-yl)thiophene 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.
