About us:

Anant Pharmaceuticals Pvt. Ltd. was established with an aim to provide custom synthesis

support to Pharmaceutical industry. Anant is a Sanskrit word meaning endless.

In the overcrowded domain of custom synthesis Anant marks is difference by focusing on

custom synthesis of impurity and metabolite products only. As our name says there are endless

opportunities in the impurity and metabolite synthesis field. The synthesis of impurities

requires expertise in synthetic as well as analytical chemistry, especially an understanding of

reactions leading to formation of impurities is essential. At Anant we aim to achieve a status of

partner of choice through excellent service and transparent communications with our client.

Timely delivery and consistent quality is our mission.

With a quest for constant improvement and thirst for challenges we seek projects with highest

level difficulties and strive to achieve the targets on time. With our team of experts and

qualified man power we have synthesized impurities of most difficult products like

Azithromycin, Chloic acid, Fusidic Acid etc.

All the impurity standards are tested using the methods reported in the current pharmacopeia

whenever available or with the method compatible with customer’s specific analytical

procedures. Products are characterized by sophisticated analytical methods like LCMS & NMR.

The characterization data is supplied with the sample along with the standard COA. List of our

impurity products is given in this document, for any requirements please contact us on the

address given below.

All our products are exported through our sister concern M/s Anant Laboratories all over the world.
