Chemical Structure
Description
As a certified reference material (CRM), 2-Mesityl-2-oxoacetic acid 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.
2-Mesityl-2-oxoacetic acid (CAS 3112-46-7), molecular formula C11H12O3 and molecular weight 192.21 g/mol, is a CATO reference standard with documented purity and traceability.
2-Mesityl-2-oxoacetic acid (C11H12O3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
