    I am a manager of our company’s parenteral drug extractable and leachable team. After a new leachable is identified by mass spectrometry, we need to get structural confirmation and quantitation using authentic standard. Sometime the leachable is not commercially available and needs custom synthesis. AxisPharm synthesized 4 compounds for us in 2020. AxisPharm has already delivered the product ahead of the timeline. Our last compound was for an urgent method development and validation work at a CRO to fulfil a commitment to FDA. The compound was not in stock at AxisPharm and need custom synthesis. We placed the order on 22nd Oct, and AxisPharm shipped the compound to the CRO on 26th Oct. I am very happy with working with AxisPharm and would recommend AxisPharm as a trusted company for your next custom synthesis.
