Chemical Structure

千层纸素A-7-葡萄糖苷 CAS 36948-77-3 chemical structure

Description

千层纸素A-7-葡萄糖苷 (CAS 36948-77-3) is a high-purity analytical reference standard with the molecular formula C22H22O10 and a molecular weight of 446.40 g/mol.

Structurally, 千层纸素A-7-葡萄糖苷 (C22H22O10) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 446.40 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.

CATO manufactures 千层纸素A-7-葡萄糖苷 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
