Camphor Powder Extra Pure

Whatsapp Order

Camphor Powder Extra Pure is a high-purity, crystalline white solid known for its distinct, penetrating aroma and volatility, making it valuable in laboratory applications involving sublimation, volatility studies, and organic compound identification. It is frequently used as a standard in melting point determination and as a model compound for exploring phase changes, vapor pressure, and diffusion behavior. In organic synthesis, it serves as a precursor or reagent in oxidation-reduction reactions. The extra pure grade ensures low impurity levels, which is essential for precise analytical and research work. Due to its flammable and volatile nature, it should be handled in well-ventilated areas and stored in tightly sealed containers away from heat and open flames.

Description

Primary Uses
Sublimation Demonstrations

Used to illustrate the sublimation process (solid to vapor without passing through liquid), making it a popular teaching tool in physical chemistry labs.

Organic Compound in Synthesis Experiments

Acts as a starting material or intermediate in organic synthesis, especially for preparing camphor derivatives.

Phase Transition Studies

In thermodynamics labs, used to demonstrate phase changes, volatility, and behavior of volatile solids under controlled temperatures.

Crystallization & Purity Studies

Utilized in crystallization experiments to study morphology and purification techniques through recrystallization.

Standard in Melting Point Determination

Sometimes used as a known compound in calibration of melting point apparatus due to its sharp and characteristic melting point.

Secondary Uses
Insect Repellent Studies

Tested in bioassays or entomology labs to observe repellent activity and volatilization behavior.

Aroma Compound for Sensory Testing

Occasionally included in olfactory experiments or sensory science setups to study detection thresholds and perception.

Solvent Behavior in Herbal Extracts

Used in labs focused on natural product chemistry or phytochemistry to study extraction from botanical samples.

Historical Chemistry Demonstrations

Common in reenactments or educational modules illustrating 19th-century organic chemistry methods.

SAFETY HANDLING PRECAUTIONS

Personal Protective Equipment (PPE):

Wear safety goggles, chemical-resistant gloves, lab coat, and use a dust mask or respirator in case of dust formation.

Handling:

Handle in a well-ventilated area or under a fume hood.

Avoid contact with skin, eyes, and clothing.

Keep away from heat, flames, and sources of ignition — camphor is combustible.

Storage:

Store in a cool, dry, and well-ventilated area, away from oxidizing agents and sources of heat.

Keep the container tightly closed and properly labeled.

FIRST AID MEASURES
Inhalation:

Remove to fresh air.

If breathing is difficult, give oxygen.

Seek medical attention if symptoms persist.

Skin Contact:

Wash with plenty of water and soap.

Remove contaminated clothing.

Seek medical advice if irritation develops.

Eye Contact:

Rinse cautiously with water for 15 minutes.

Lift eyelids occasionally.

Seek medical attention.

Ingestion:

Do not induce vomiting.

Rinse mouth with water.

Seek immediate medical attention. Camphor can be toxic if ingested in sufficient quantities.

FIRE FIGHTING MEASURES
Flammability:

Highly flammable. May form combustible dust-air mixtures.

Extinguishing Media:

Use dry chemical, CO₂, or alcohol-resistant foam.

Do not use water jets directly on the burning powder.

Hazardous Combustion Products:

Emits toxic fumes, including carbon monoxide and carbon dioxide.

Firefighter Protection:

Use self-contained breathing apparatus (SCBA) and full protective gear.
