Ethyl isobutyrate Safety Profile

Moderately toxic by intraperitoneal route. A skin irritant. Flammable liquid. A very dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. To fight fire, use foam, CO₂, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS.

Hazard Codes: F Irritant Xi
Risk Statements: 11-36/37/38
R11:Highly flammable.
R36/37/38:Irritating to eyes, respiratory system and skin.
Safety Statements: 16-26-36-36/37/39
S16:Keep away from sources of ignition.
S26: In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
S36:Wear suitable protective clothing.
S36/37/39:Wear suitable protective clothing, gloves and eye/face protection.

Ethyl isobutyrate Specification

Ethyl isobutyrate ,its cas register number is 97-62-1. It also can be called Ethyl-2-methylpropanoat ; Propanoic acid, 2-methyl-, ethyl ester and 2-Méthylpropanoate d'éthyle . It is hazardous,so the first aid measures and others should be known. Such as: When on the skin: first,should flush skin with plenty of water immediately for at least 15 minutes while removing contaminated clothing. Secondly,Get medical aid. Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Then get medical aid soon. While ,it's Inhaled: Remove from exposure and move to fresh air immediately.Give artificial respiration while not breathing. When breathing is difficult, give oxygen. And as soon as to get medical aid. Then you have the ingesting of the product : Wash mouth out with water,and get medical aid immediately.
In addition, Ethyl isobutyrate (CAS NO.97-62-1) can be stable under normal temperature and pressure conditions.It is not compatible with strong oxidizing agents, and you must not take it with incompatible materials. And also prevent it to broken down into hazardous decomposition products: carbon dioxide, carbon monoxide.
