Custom Synthesis and Fine Chemical

We Synthesize customised molecules for your niche segments and scalability improvements

Custom synthesis is the process where a molecule is made exclusively for a particular client according to specifications at their scale. It is one of the options available for pharmaceutical companies requiring active pharmaceutical ingredients (APIs), intermediates, fine chemicals, reference standards, impurities or metabolites needed to launch their research and development projects. Custom synthesis is essential to the pharmaceutical companies since many of these compounds can sometimes be very difficult to find or hard to synthesize.

Custom synthesis provides the platform necessary for clients’ to accelerate their projects to market.
