Chemical Structure

2,5-Diphenylselenophene CAS 18782-55-3 chemical structure

Description

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.

CATO supplies 2,5-Diphenylselenophene (CAS 18782-55-3), a certified reference material (molecular formula C16H12Se, MW 283.23 g/mol) for analytical method development and quality control.

2,5-Diphenylselenophene (C16H12Se) contains a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
