Our scientists apply high-performance microfiltration to accomplish sterilization. We often use this technology with powder, which is dissolved, filtered and crystallized. Microfiltration is nondestructive, which means it differs fundamentally from traditional sterilization methods. We offer many techniques to precisely control the physical properties of the final product.

Propane-phosphonic Acid Anhydride – T3P

From development to commercial scale requirements, we can help you develop a superior reagent with our T3P application program.

We have over nearly 30 experience in coupling reactions for a variety of chemical reactants from amides, heterocycles and esters and to carbon-carbon bonds. This allows us to provide a free application program for T3P process development carried out under a strict confidentiality, giving you complete control of your intellectual property.

With proper optimization and process development support from us, T3P is proven to be the optimal reagent in many cases. Our expertise allows integration of the coupling and extraction steps required and provides an optimum solution for commercial scale-up.

T3P, propanephosphonic acid anhydride, is an exceptional reagent for amide/peptide bond formation. T3P is very easy to use and combines excellent reaction selectivity, almost no epimerization, high product purities and excellent yields. Because of its properties, hazardous additives, such as explosive HOBt, are not required.

Additionally, the T3P reagent is non-toxic, non-allergenic/non-sensitizing and the salt by-products are nonhazardous and completely water soluble.

It works well in other condensation reactions, such as esterifications and may be used as a mild reagent for alcohol oxidations and the Lossen rearrangement.

T3P provides excellent selectivity and high yields with simple product isolation by liquid/liquid extraction. Its advantages translate into high-quality products and improved economics, particularly for large-scale, complex coupling reactions.
