Cerilliant, located in Round Rock, Texas, a suburb of Austin, is a global leader in providing certified reference standards for critical applications. The company has been providing certified reference materials for over 30 years. Cerilliant is an ISO Guide 34 and ISO/IEC 17025 accredited ISO 13485 and ISO 9001 certified company and has grown to become a world leader in providing a wide variety of high quality reference standards and materials for forensic/toxicology, clinical/diagnostic, environmental, nutraceutical, and pharmaceutical analysis. Formerly known as the Analytical Reference Materials Division of Radian International, the company began producing chemical reference standards in 1980 to address the needs of the emerging environmental testing industry and was the first to produce 13C labeled chlorinated dioxins and furans in cooperation with Cambridge Isotope Laboratories. Cerilliant was also the first to offer isotope-labeled drugs-of-abuse reference standards to the forensic drug testing industry and pioneered DEA exempt preparations of controlled substances in solution. In 2000, Radian’s parent, URS Corporation, made the decision to divest the division. Cerilliant was formed following the purchase of the division by private investors. Since its formation in August 2000, Cerilliant has steadily grown from 23 to over 70 employees and serves more than 2000 active customers, including federal and state governmental organizations and laboratories, private laboratories, hospitals, universities, pharmaceutical companies, contract research organizations, and analytical instrument, medical device and test kit manufacturers. Cerilliant’s products are distributed throughout the entire world.
