General description

Chemicals play an important role in the stabilization of a biologic drug during its manufacturing and formulation process – for instance, by preventing aggregation. We offer a wide range of high-quality stabilizers, buffers and salts to successfully purify and formulate your biomolecules. Specifically developed for high-risk applications, they are low in bioburden and endotoxins.
As part of our Emprove® Program, our raw materials are offered with extensive documentation facilitating compliance of your pharma and biopharma product, full supply chain transparency and risk mitigation. Our SAFC® portfolio of high-quality products for biopharmaceutical and pharmaceutical formulation and production withstands strict quality control procedures and is produced according to applicable cGMP guidelines.

Application

Tri-n-butyl phosphate is used widely as a solvent along with either TritonTM X100 or Tween® in solvent detergent treatment for viral inactivation procedures especially for plasma derived therapeutics.
Due to its low microbial and endotoxin limits, Tri-n-butyl phosphate Emprove® Expert is especially suitable for high-risk applications.
