Organic Bases

Organic bases are critical reagents in organic synthesis due to their multifaceted roles in several applications. As opposed to their inorganic counterparts, these species are readily soluble in organic solvents making them suitable for homogenous reaction mixtures. Sigma-Aldrich carries a variety of organic bases that vary in level of basicity, for example:
  • Organolithiums
  • Grignard Reagents
  • Amines
  • N-Heterocyclic Compounds
  • Tetraalkylammonium and phosphonium hydroxides
  • Metal Alkoxides and Amides
  • Metal Silanoates

While the majority of the portfolio of organic bases is used in homogeneous mixtures, the catalog also carries polymer-bound organic bases for solid supported synthesis. Some of the products within this portfolio display sensitivity to both moisture and air. To help protect these organic bases from degradation, Sigma-Aldrich provides top-quality packaging in Aldrich® Sure/Seal™ bottles to prolong the lifetime of these reagents. A growing list of products are also being transitioned into exclusive 25 mL Sure/Seal packaging with the priorities of reducing waste and decomposition of more unstable organic bases by requiring fewer needle entries to consume the reagent volume.
