3-[(2-Benzoyl-3-oxo-3-phenylprop-1-en-1-yl)amino]-2H,5H-pyrano[3,2-c]chromene-2,5-dione CAS 220957-61-9

Description

As a certified reference material (CRM), 3-[(2-Benzoyl-3-oxo-3-phenylprop-1-en-1-yl)amino]-2H,5H-pyrano[3,2-c]chromene-2,5-dione 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.

3-[(2-Benzoyl-3-oxo-3-phenylprop-1-en-1-yl)amino]-2H,5H-pyrano[3,2-c]chromene-2,5-dione (CAS 220957-61-9), molecular formula C28H17NO6 and molecular weight 463.44 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-[(2-Benzoyl-3-oxo-3-phenylprop-1-en-1-yl)amino]-2H,5H-pyrano[3,2-c]chromene-2,5-dione (C28H17NO6) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
