Chemical Structure

2-Methyl-1,3-di-p-tolylpropane-1,3-dione CAS 27450-45-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 2-Methyl-1,3-di-p-tolylpropane-1,3-dione (CAS 27450-45-9), a certified reference material (molecular formula C18H18O2, MW 266.33 g/mol) for analytical method development and quality control.

2-Methyl-1,3-di-p-tolylpropane-1,3-dione (C18H18O2) contains a steroid core, a hydroxyl group, an ether linkage. 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 2-Methyl-1,3-di-p-tolylpropane-1,3-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.
