Chemical Structure
Description
The occurrence of 5-Formyl-1,3-phenylene diacetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Formyl-1,3-phenylene diacetate (CAS 57179-37-0), molecular formula C11H10O5 and molecular weight 222.19 g/mol, is a CATO reference standard with documented purity and traceability.
5-Formyl-1,3-phenylene diacetate (C11H10O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 5-Formyl-1,3-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.
