Revvity, 6002144, Bis-MSB Scintillator, 100 g

Overview
Bis-MSB, IUPAC preferred name 1,4-bis[2-(2-methylphenyl)ethenyl]benzene, has an aromatic ring structure fundamental for fluorescent properties.
Bis-MSB is a secondary scintillator or wavelength shifter and converts shorter wavelength light to longer wavelength light that can be detected by Liquid Scintillation Analyzers (LSA) such as a TriCarb or Quantulus GCT. Bis-MSB is a high solubility secondary fluor and enhances the light yield in LSC when used with PPO. Bis-MSB is characterized by its high quantum yield and blue emission.
The exact fluorescence maximum can vary slightly depending on the solvent used. For example, in cyclohexane, the maximum is ~415 nm, while in heptane, it's slightly lower at 416 nm.
The Molecular Formula of Bis-MSB is C24H22, a melting point of 180 - 182°C and a fluorescence maximum of 415 nm. Maximum Emission Wavelength (Em-~415 nm
