SHORT DESCRIPTION

Isobutyl Alcohol Extra Pure is a high-purity, branched-chain aliphatic alcohol with the chemical formula C₄H₁₀O. It appears as a clear, colorless liquid with a characteristic odor and is highly soluble in organic solvents while only moderately soluble in water. This compound is commonly used in laboratories as a solvent for resins, oils, and other organic compounds, as well as in the synthesis of esters and plasticizers. Due to its volatility and purity, Isobutyl Alcohol is valuable in analytical procedures, chemical research, and as a standard in gas chromatography. Proper storage in tightly sealed containers away from heat and ignition sources is essential due to its flammability.

Description

USES

Table of Contents

Primary Laboratory Uses:

Solvent in Organic Synthesis:
Commonly used as a medium for reactions or for dissolving organic compounds, especially in esterification, extraction, and purification processes.
Intermediate in Ester Production:
Frequently used to produce isobutyl esters, such as isobutyl acetate, which are studied for their fragrance and solvent properties.
Chromatography Sample Preparation:
Employed in the preparation and dilution of samples for gas chromatography (GC) or thin-layer chromatography (TLC).

Secondary Laboratory Uses:

Reagent in Biodiesel Research:
Studied as an alternative alcohol in transesterification reactions for biodiesel production experiments.
Boiling Point & Distillation Studies:
Used in physical chemistry labs to explore boiling point behavior, azeotropes, and distillation techniques.
Study of Alcohol Functional Group Behavior:
Ideal for experiments demonstrating hydroxyl group reactivity, especially in substitution and oxidation reactions in organic chemistry labs.

Use a fume hood or ensure adequate ventilation to avoid vapor inhalation.

Handling:

Avoid breathing vapors or mist.
Prevent contact with eyes, skin, and clothing.
Use only in well-ventilated areas.
Keep away from heat, sparks, open flames, and sources of ignition.

Storage:

Store in a tightly closed container in a cool, dry, and well-ventilated area.
Keep away from strong oxidizing agents and incompatible materials.
Ground and bond containers when transferring.

FIRST AID MEASURES

Inhalation:

Move people to fresh air.
Administer oxygen if breathing is difficult.
Seek medical attention if symptoms persist.

Skin Contact:

Wash affected areas thoroughly with soap and water.
Remove contaminated clothing.
Seek medical advice if irritation develops.

Eye Contact:

Rinse cautiously with water for at least 15 minutes.
Remove contact lenses if present and easy to do.
Seek immediate medical attention.

Ingestion:
