Chemical Structure
Description
2,3-Dichloro-3-(2-methylphenyl)propiophenone (CAS 898789-93-0) is a high-purity analytical reference standard with the molecular formula C16H14Cl2O and a molecular weight of 293.19 g/mol.
2,3-Dichloro-3-(2-methylphenyl)propiophenone (C16H14Cl2O) contains 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; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 2,3-Dichloro-3-(2-methylphenyl)propiophenone 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.
