Carbon Disulfide 99% Extra Pure

Whatsapp Order

Carbon Disulfide 99% Extra Pure is a volatile, colorless to pale yellow liquid with a strong, characteristic odor, valued in laboratory settings for its high purity and solvency power. Commonly used as a non-polar solvent, it is ideal for dissolving sulfur, fats, resins, and phosphorus in analytical and synthetic chemistry. Its role extends to studying reaction kinetics, extraction processes, and as a reagent in organic synthesis involving thiocarbonyl compounds. Due to its low flash point and high volatility, it is also utilized in vapor pressure and flammability studies. The 99% extra pure grade ensures minimal impurities, critical for sensitive applications. It must be handled in a well-ventilated fume hood and stored away from heat, sparks, and oxidizing agents.

Keep tightly sealed in airtight containers.

Ground containers properly to avoid static discharge.

FIRST AID MEASURES
Inhalation:

Move to fresh air immediately.

Provide oxygen or CPR if breathing is difficult or stopped.

Call emergency services immediately.

Skin Contact:

Remove contaminated clothing.

Wash with plenty of soap and water for at least 15 minutes.

Seek medical attention.

Eye Contact:

Rinse cautiously with water for at least 15 minutes while lifting eyelids.

Seek immediate medical care.

Ingestion:
