Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 222.24 g/mol gives Dimethyl 2,2-(1,4-phenylene)diacetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dimethyl 2,2-(1,4-phenylene)diacetate (CAS 36076-25-2), molecular formula C12H14O4 and molecular weight 222.24 g/mol, is a CATO reference standard with documented purity and traceability.
Dimethyl 2,2-(1,4-phenylene)diacetate (C12H14O4) 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.
As a certified reference material (CRM), Dimethyl 2,2-(1,4-phenylene)diacetate 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.
