Chemical Structure
Description
The occurrence of 1,3-Isobenzofurandione, 3a,4,7,7a-tetrahydro-, polymer with 1,3-butanediol and oxybis[propanol] is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3-Isobenzofurandione, 3a,4,7,7a-tetrahydro-, polymer with 1,3-butanediol and oxybis[propanol] (CAS 72403-53-3) is a high-purity analytical reference standard with the molecular formula C8H8O3C6H14O3C4H10O2 and a molecular weight of 376.45 g/mol.
1,3-Isobenzofurandione, 3a,4,7,7a-tetrahydro-, polymer with 1,3-butanediol and oxybis[propanol] (C8H8O3C6H14O3C4H10O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
