Chemical Structure
Description
Jasmonic Acid Impurity 2（rac-trans Jasmonic Acid Methyl Ester） (C13H20O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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).
Jasmonic Acid Impurity 2（rac-trans Jasmonic Acid Methyl Ester） (CAS 20073-13-6), molecular formula C13H20O3 and molecular weight 224.30 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Jasmonic Acid Impurity 2（rac-trans Jasmonic Acid Methyl Ester） meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
