Chemical Structure

Cinobufagin CAS 470-37-1 chemical structure

Description

CATO supplies Cinobufagin (CAS 470-37-1), a certified reference material (molecular formula C26H34O6, MW 442.54 g/mol) for analytical method development and quality control.

The molecular framework of Cinobufagin (C26H34O6) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), Cinobufagin 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.
