2,2':5',2''-Terselenophene CAS 67308-30-9 chemical structure

Description

CATO supplies 2,2':5',2''-Terselenophene (CAS 67308-30-9), a certified reference material (molecular formula C12H8Se3, MW 389.07 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H8Se3, 2,2':5',2''-Terselenophene contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 389.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
