ORGANIC STRONG BASES - Envure™

SACHEM's manufacturing technologies enable the production of high purity quat hydroxides that are available in water and in organic solvents. SACHEM's Envure™ line of high purity strong bases are low metal containing. They feature large organic cations and have low contaminant levels. SACHEM’s Envure™ line of strong organic base products forms the foundation of many critical formulations in lithography, cleaning, planarizing and etching applications. 
Envure™ strong bases bring a new purity level to your most demanding processes with:

  • Low metal ion and halide contamination (500ppb) allows the flexibility of integrating other lower purity components in applications with overall "contamination budgets" that cannot be exceeded. (Download the product datasheet below for specification details).
  • Good organic solubility and increased performance (organic solubility is critical to applications in which the base must interact with an organic compound or in organic media); useful in phase transfer catalysis (PTC); solubility in non-aqueous solvents promotes greater nucleophilicity; replaces expensive crown ethers in some applications.

  • Elimination of sodium or potassium contamination to prevent side reactions and unwanted byproducts; alternative to metal hydroxides, hydrides and alkoxides in many systems.

Envure™ high purity strong bases have applications in electronics, ceramics, silicones, inks, coatings, strong base catalysis, polymers, industrial cleaning, phase transfer catalysis and zeolites. 


SACHEM is the only company in the world offering these high purity products. Whether you require the new purity level that Envure™ high purity strong bases can bring to your processes, or a more technical grade strong base, SACHEM can meet your specific needs. We offer excellent logistics support to supply Envure™ anywhere in the world consistently and reliably. Contact us to learn more about how SACHEM products and services can improve your process.
