Chemical Properties
clear colorless liquid
Uses
Isobutyric anhydride was used in the synthesis of 4-
O-isobutyryl derivative via reaction with octyl β-D-glucopyranoside in the presence of C
2-symmetric chiral 4-pyrrolidinopyridine as a catalyst.
Uses
Chemical intermediate.
Definition
ChEBI: An acyclic carboxylic anhydride of isobutyric acid. Metabolite observed in cancer metabolism.
General Description
A colorless liquid. Flash point 139°F. Burns skin and eyes. Vapors are heavier than air.
Air & Water Reactions
Flammable. Reacts exothermically with water or moisture-containing materials to form isobutyric acid.
Reactivity Profile
Isobutyric anhydride reacts exothermically with water. The reactions are sometimes slow, but can become violent when local heating accelerates their rate. Acids accelerate the reaction with water. Incompatible with a cids, strong oxidizing agents, alcohols, amines, and bases.
Hazard
Strong irritant to tissue.
Health Hazard
May cause toxic effects if inhaled or ingested/swallowed. Contact with substance may cause severe burns to skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Fire Hazard
Flammable/combustible material. May be ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
