Ptelatoside B CAS 90852-99-6 chemical structure

Description

CATO manufactures Ptelatoside B 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.

Ptelatoside B (CAS 90852-99-6) is a high-purity analytical reference standard with the molecular formula C20H28O10 and a molecular weight of 428.43 g/mol.

Ptelatoside B (C20H28O10) contains a flavonoid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
