Chemical Structure
Description
2-(3-(Tert-butyl)-4,9-dimethyl-7-oxo-7h-furo[2,3-f]chromen-8-yl)acetic acid (CAS 853892-50-9) is a high-purity analytical reference standard with the molecular formula C19H20O5 and a molecular weight of 328.36 g/mol.
Structurally, 2-(3-(Tert-butyl)-4,9-dimethyl-7-oxo-7h-furo[2,3-f]chromen-8-yl)acetic acid (C19H20O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 328.36 g/mol, it falls into the moderately-high-molecular-weight range. 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), 2-(3-(Tert-butyl)-4,9-dimethyl-7-oxo-7h-furo[2,3-f]chromen-8-yl)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.
