Chemical Structure
Description
The occurrence of Methyl 5,5-bis(4-hydroxyphenyl)pentanoate is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 5,5-bis(4-hydroxyphenyl)pentanoate (CAS 633300-55-7) is a high-purity analytical reference standard with the molecular formula C18H20O4 and a molecular weight of 300.35 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, Methyl 5,5-bis(4-hydroxyphenyl)pentanoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
