Chemical Structure
Description
2-(1-Chloroethyl)-1,3,5-trimethylbenzene (CAS 51270-90-7), molecular formula C11H15Cl and molecular weight 182.69 g/mol, is a CATO reference standard with documented purity and traceability.
2-(1-Chloroethyl)-1,3,5-trimethylbenzene (C11H15Cl) contains chlorine substitution, an aromatic ring 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 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 2-(1-Chloroethyl)-1,3,5-trimethylbenzene 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.
