Chemical Structure

Picropodophyllin CAS 477-47-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 414.41 g/mol gives Picropodophyllin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Picropodophyllin (CAS 477-47-4), a certified reference material (molecular formula C22H22O8, MW 414.41 g/mol) for analytical method development and quality control.

Picropodophyllin (C22H22O8) 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
