2-Vinylselenophene (CAS 58963-90-9), molecular formula C6H6Se and molecular weight 157.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Vinylselenophene (C6H6Se) is characterized by an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, 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).
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.
