A colorless liquid. Slightly denser than water and insoluble in water. Flash point near 100°F. May irritate skin and eyes. Toxic by ingestion and inhalation. Used to make other chemicals.

Highly flammable. Insoluble in water.

GLYCIDALDEHYDE is an epoxide and an aldehyde. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation. Epoxides are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts.

TOXIC; may be fatal if inhaled, ingested or absorbed through skin. Inhalation or contact with some of these materials will irritate or burn 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.

HIGHLY FLAMMABLE: Will be easily 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 and poison hazard indoors, outdoors or in sewers. May polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Glycidyldehyde is and epoxide used to synthesize other chemicals. It has been used in the fin ishing of wool and the tanning of leather and surgical sutures in the U.K. It has been tested as a disinfectant.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, includ ing resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medi cal attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

UN2622 Glycidaldehyde, Hazard Class: 3; Labels: 3-Flammable liquid, 6.1-Poisonous materials. The addition of antioxidant stabilizers to shipments of alde hydes may retard autoxidation.

Glycidaldehyde may undergo violent polymerization when subjected to heat, strong sunlight, or contamination. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explo sions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. When heated or in contact with catalysts, epoxides may cause violent polymer ization. Epoxides are incompatible with reducing agents and oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materi als, strong bases, strong acids, oxoacids, and epoxides. May react, possibly violently, with water in the presence of acid and other catalysts. Reacts with alcohols, amines, and other active hydrogen compounds. Slowly hydrolyzes in water.

Glycidaldehyde is a mobile, colorless liquid with a pungent odor.There is a pronounced aldehyde-like odor at low levels. Voluntary exposure to serious lung-irritating levels is unlikely.

Glycidyl aldehyde is a colorless liquid. It has a pungent, aldehyde-like odor.

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations govern ing storage, transportation, treatment, and waste disposal.

Butylene oxide is used as a cross-linkingagent in wool finishing, for tanning andfat liquoring of leather, and to insolubilizeprotein.

Glycidaldehyde is prepared from the hydrogen peroxide epoxidation of acrolein. It is suggested as a bifunctional chemical intermediate and as a cross-linking agent for textile treatment, leather tanning, and protein insolubilization.

ChEBI: Glycidaldehyde is an epoxide.
