PHARMACEUTICAL IMPURITIES
We are fastest growing company in sourcing & supplying of Impurity Standards.
We have developed a wide range of specialist compounds principally for use in research and development programs. Qualification of the impurities is a process of acquiring and evaluating data that establishes biological safety of an individual impurity thus revealing the need and scope of impurity profiling of drugs in pharmaceutical research. Analysis is a critical part of the discovery process and we have an impressive analytical capability. The identification of impurities is done by a variety of Chromatographic and Spectroscopic techniques either alone or in combination with other techniques. Based on the product we implement those techniques. There are various methods for detecting and characterizing impurities. We apply knowledge and creativity to help our customers achieve breakthroughs in the discovery and development of new products. Our experience has enabled us to design synthetic routes and optimize chemical processes. We build productive and collaborative partnerships with our customers.
