Selenopheno[3,4-b]selenophene CAS 250-71-5 chemical structure

Description

CATO supplies Selenopheno[3,4-b]selenophene (CAS 250-71-5), a certified reference material (molecular formula C6H4Se2, MW 234.02 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H4Se2, Selenopheno[3,4-b]selenophene contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 234.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
