DetectX® Palladium API Screening Fluorescent Detection Kit

The PdX^™ Palladium API Screening Fluorescent Detection Kit is designed to allow rapid screening of methods for Pd removal from solutions of APIs in DMF, Acetonitrile, NMP, Ethanol, dilute HCl and Toluene. Standards or diluted samples are pipetted into a microtiter plate along with supplied Detection Reagent and Sodium Borohydride reducing agent. After 30 minutes the intensity of the generated fluorescence is read at 525nm in a microtiter plate reader. Fluorescence is proportional to Pd level. No acid digestion required.

In recent years, many new synthetic transformations have been developed that use palladium (Pd) compounds for the catalysis of carbon-carbon and carbon-heteroatom coupling reactions such as the Buchwald-Hartwig, Heck, Sonogashira, Suzuki-Miyaura, and Tsuji-Trost transformations. These reactions have found increased popularity for pharmaceutical processes as they utilize a wide-range of functional groups to build complicated molecules. However palladium-catalyzed reactions present a problem in that the palladium can often be retained in the isolated API product. Current FDA and EAEMP regulations limit all platinum group (Pt, Pd, Ir, Rh, Ru, Os) metal contamination (as a group) to less than 5-10 ppm. The standard methods of quantifying palladium in APIs are atomic absorption analysis, x-ray fluorescence, or inductively-coupled plasma mass spectroscopy (ICP-MS). These expensive instruments dictate a highly trained scientist to operate, suffer from cross-contamination of the probe and require scrupulous clean up methodology.
