1,5-Bis(5-chloro-2-methylthiophen-3-yl)pentane-1,5-dione CAS 219537-95-8

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.

1,5-Bis(5-chloro-2-methylthiophen-3-yl)pentane-1,5-dione (CAS 219537-95-8), molecular formula C15H14Cl2O2S2 and molecular weight 361.31 g/mol, is a CATO reference standard with documented purity and traceability.

1,5-Bis(5-chloro-2-methylthiophen-3-yl)pentane-1,5-dione (C15H14Cl2O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. 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).

CATO manufactures 1,5-Bis(5-chloro-2-methylthiophen-3-yl)pentane-1,5-dione 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.
