ISOAPI-D Power of Deuterium: Smarter, Stronger Therapeutics

"ISOAPI-D reagents are designed to support the development of next-generation active pharmaceutical ingredients (APIs) by leveraging the unique benefits of deuterium incorporation," said Cliff Caldwell, CEO of CIL. "With ISOAPI-D, our customers gain access to a trusted and secure supply chain, ensuring they have consistent, reliable access to the materials they need for robust and efficient drug development."

CIL's global manufacturing network, including facilities in North America, Europe, and Asia, enables CIL to provide a diversified and resilient supply chain for pharmaceutical partners. Every ISOAPI-D product is manufactured in ISO 9001-certified facilities, ensuring the highest standards of quality, regulatory compliance, and full traceability throughout the production process.

A core component of the ISOAPI-D line is heavy water (D₂O), which is sourced exclusively from approved suppliers. This product is fully traceable and tritium-free, aligning with stringent safety and regulatory requirements of the pharmaceutical industry.

The ISOAPI-D range also features advanced intermediates that allow for more streamlined synthetic pathways. By reducing the number of synthesis steps and optimizing production efficiency, these intermediates can help lower manufacturing costs and accelerate the time to market for new therapeutics.

Since 1981, CIL has been a trusted supplier of premium deuterated materials to leading pharmaceutical and biotechnology companies worldwide. This longstanding commitment to quality and reliability continues with the launch of ISOAPI-D, offering customers a secure, high-quality supply of essential reagents and reducing operational risk in their development pipelines.

"ISOAPI-D represents the next step in our ongoing mission to support pharmaceutical innovation," said Tasha Agreste, Business Development Manager Deuterated Reagent Applications, at CIL. "Our expanded manufacturing capabilities, rigorous quality standards, and decades of experience position CIL as a reliable partner for the industry's evolving needs."

Visit CIL at CPhI Frankfurt, Stand #2.0G2, October 28-30, to discover ISOAPI-D, the future of deuterated chemistry for pharmaceuticals.
