Research and Development

RUI Lab set up a Research and Development Centre in 3000 square feet lab space at Visakhapatnam, Andhra Pradesh. It has helped us to make a successful entry into an enhanced product portfolio. The R&D Centre facility focuses on generic API and intermediates development.

It is committed to offering superior and affordable solutions for products with intrinsic challenges at the chemistry and engineering areas, while creating its own intellectual property. Our R&D Centre conforms to international quality standards and houses advanced and up to date equipment. It has one of the most advanced infrastructures for both basic and applied research. The research facility is equipped with state-of-the-art infrastructure required to carry out research activities like process & analytical chemistry.

We invest into R&D aiming to design / develop / optimize novel, non-infringing, commercially viable, high-safety and eco-friendly synthetic processes in line with regulatory requirements that create intellectual wealth and commercialize cost-effective, quality products in diversified therapeutic areas.

RUI Lab strives and continues to work in the path of moving towards organisational and business excellence and at the same time believes to be an example as a contributor and work towards national aspirations.
