(4-Propionyl-phenoxy)-acetic acid CAS 6501-31-1

Description

Compared with other compounds in its class, the molecular weight of 208.21 g/mol gives (4-Propionyl-phenoxy)-acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(4-Propionyl-phenoxy)-acetic acid (CAS 6501-31-1), molecular formula C11H12O4 and molecular weight 208.21 g/mol, is a CATO reference standard with documented purity and traceability.

(4-Propionyl-phenoxy)-acetic acid (C11H12O4) 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), (4-Propionyl-phenoxy)-acetic 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.
