GHS Hazard Classification

Reported hazard statements	H302, H332 (59.3%), H360 (40.7%), H373 (98.9%), H400 (98.9%), H410 (99.4%), H341, H351

Documented Uses

• Used in organic syntheses; [HSDB]
• Often used as an oxidizing agent in organic syntheses because it is highly selective in cleaving vicinal glycols. It also readily cleaves alpha-hydroxy acids, such as oxalic acid, at room temperature. Another use is for the introduction of acetoxy groups in organic molecules.
• Prepd from Pb3O4 and glacial acetic acid preferably in the presence of some acetic anhydride; ... Prepn by electrolysis.[The Merck Index, Fourteenth Edition (2006)
• ... Prepared by adding warm, anhydrous, glacial acetic acid to red lead (Pb3O4) and subsequently cooling the solution.
• Acetic acid, lead(4+) salt (4:1): ACTIVE
• 10 to 30 grams for and adult human (lead salts). (T17)
