Propionic Anhydride

CAS RN: 123-62-6

Range of Toxicity

A) TOXICITY: Serious burns are less likely if the pH >3. Injury is usually greater with either a large ingestion (usually deliberate), or a high concentration acid (usually not a household product). With highly concentrated liquids (eg, 20N), severe burns may occur in up to 100% of all patients.
B) In a case series of unintentional caustic ingestions (mixed liquid and solid, acids and bases) among children, the incidence of significant esophageal or gastric burns was 5% to 35%. However, adults with deliberate acid ingestions are more likely to develop significant esophageal and/or gastric burns (40% to 95%).
