Polystyrene, Analytical Standard, For GPC, 800, MilliporeSigma™ Supelco™
Polystyrene (for GPC, 800), a synthetic thermoplastic, is useful in a broad range of applications due to its rigidity, low specific weight, high chemical resistance, mechanical flexibility, biocompatibility and good processability.
2,6-Dimethoxyphenol, ≥98% (GC), MilliporeSigma™ Supelco™
2,6-Dimethoxyphenol can find applications mainly as a substrate of laccases catalysis and also determine its activity in aqueous solution. It can also be used as a potential marker compound in particular for emission of smoke in the atmosphere from wood.
Naringin, ≥95% (HPLC), MilliporeSigma™ Supelco™
Naringin is a naturally occurring flavone glycoside, which may possess many pharmacological properties like anti-inflammatory, anti-oxidant and anti-apoptotic activity. It is widely found in fruits like grapes and oranges.
PESTANAL™ 4-Isopropylthioxanthone, MilliporeSigma™ Supelco™
A mixture of 4-isopropylthioxanthone and 2-isopropylthioxanthone can be used as photoinitiator in ultraviolet(UV)inks, which finds applications in plastic or paper based packaging materials.
