• Recent ClinicalTrials: A Study of PM8002 (Anti-PD-L1/VEGF) in Combination With Chemotherapy in Patients With ES-SCLC
• Recent EU Clinical Trials: This Phase III multi-center study of DTaP-IPV-Hib, with or without Hep B, used as a booster vaccine in healthy infants and toddlers will be conducted with two controlled, blind-observer trial arms in Germany and the Czech Republic and an open-label trial arm in Spain. Subjects in Germany and the Czech Republic will receive (at 11 to 15 months of age) a booster dose of the same DTaP-IPV-HB-Hib investigational vaccine or the Infanrix? hexa control vaccine they received during the primary series in Study A3L39 concomitantly with a booster dose of Prevenar 13?. All subjects in Spain received 2 doses of the DTaP-IPV-HB-Hib investigational

• Inhalation Risk: Evaporation at 20 °C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly , especially if powdered.
• Effects of Short Term Exposure: The substance is irritating to the eyes and respiratory tract.

Technology Process of Platinum

There total 874 articles about Platinum which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 45.0%
