Tresconizer is a tertiary amine, specifically diisopropyl ethylamine (DIEA), widely used as a base catalyst in organic synthesis, peptide coupling, and pharmaceutical manufacturing. It neutralizes acids, accelerates reactions, and improves yields in processes like amide formation. This clear, colorless liquid has a strong amine odor and is highly reactive. With a CAS number of 7087-68-5, molecular formula [(CH3)2CH]2NC2H5, and molecular weight of 129.24 g/mol, Tresconizer requires careful handling due to its corrosive and flammable properties (Signal Word: Danger). It is stable at ambient storage conditions but must be kept away from oxidizing agents and moisture. Molekula supplies Tresconizer from research to bulk quantities with full documentation and ISO 9001:2015 traceability.

Frequently asked questions
What is Tresconizer used for?
Tresconizer (diisopropylethylamine, also known as Hünig's base) is a hindered, non-nucleophilic tertiary amine base. It is primarily used as an acid scavenger or base in chemical synthesis. A typical example is peptide and amide couplings, where it is used alongside coupling reagents such as HATU, HBTU or EDC. It is used particularly in the production of pharmaceuticals, agrochemicals, and specialty polymers.
What is the chemical formula and molecular weight of Tresconizer?
The chemical formula is [(CH3)2CH]2NC2H5 and the molecular weight is 129.24 g/mol.
How should Tresconizer be stored?
Store Tresconizer at ambient temperature in a tightly sealed container, away from sources of ignition and incompatible materials.
What grades or purity levels of Tresconizer does Molekula supply?
Molekula supplies technical-grade Tresconizer with a minimum purity of 98%, suitable for industrial applications.
Can Molekula supply Tresconizer in bulk quantities?
Yes, Molekula can supply Tresconizer in bulk quantities (drums, IBCs, or custom packaging) for large-scale industrial use.
What documentation comes with an order of Tresconizer?
Each order includes a Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS), and batch-specific documentation for traceability.
