WebPhosphorus pentasulfide is obtained by the reaction of liquid white phosphorus (P4) with sulfur above 300C. Compounds that contain covalent bonds (also called molecular compounds) exhibit different physical properties than ionic compounds. Due to hydrolysis by atmospheric moisture, P4S10 evolves hydrogen sulfide H2S, thus P4S10 is associated ...

Web33 P is a beta-emitter (0.25 MeV) with a half-life of 25.4 days. It is used in life-science laboratories in applications in which lower energy beta emissions are advantageous such as DNA sequencing. 33 P can be used to label nucleotides. It is less energetic than 32 P, giving a better resolution. WebThe ‘Substance identity’ section is calculated from substance identification information from all ECHA databases.
