  5. Product 15175, Bis[tetrakis(hydroxymethyl)phosphonium] sulfate solution, is listed as a phase transfer catalyst. What does this mean?

    A phase transfer catalyst (PTC) is a compound that promotes or accelerates a chemical reaction by allowing the migration of a specific chemical component from one phase into another phase in a heterogeneous system. A PTC is typically used when the starting materials for a reaction cannot be mixed into the same phase, which would prevent them from coming into contact each other to react. It can transport a reagent from a hydrophilic phase into the hydrophobic phase (and vice versa) so that the subsequent reaction can occur.

  6. Does Sigma-Aldrich offer any chiral phase transfer catalysts?

    We offer several chiral phase transfer catalysts to produce enantiospecific products.
