Other Reactions Possible with Nok at Room Temperature

Aldrich has collaborated with Professor Bruce Lipshutz and coworkers to provide two new additions to our Designer Surfactant portfolio: ¥ Nok (776033), also known as SPGS-550-M, was designed from a more cost-effective amphiphile, which displays comparable reactivity to its predecessors PTS (698717) and TPGS-750-M (763896, 733857, 763918). This now provides the most affordable Designer Surfactant yet, and is offered as a 2% weight aqueous solution.
