Carbon Disulfide 99% Extra Pure
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.
Primary Uses
Solvent for Non-Polar Compounds
Commonly used as a non-polar solvent for lipids, resins, phosphorus, sulfur, iodine, and rubber in analytical and organic chemistry labs.

Personal Protective Equipment (PPE):
Use chemical splash goggles, flame-resistant lab coat, and butyl rubber or Viton gloves.
Use a fume hood—never handle in open air.
Respiratory protection (full-face respirator) required for high concentrations or spill response.
Handling:
Extremely flammable and toxic—handle with extreme caution.
Avoid all sources of ignition, heat, and static discharge.
Prevent inhalation of vapors and skin contact.
Storage:
Store in a cool, flammable-storage cabinet, away from heat, oxidizers, and light.
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:
Do not induce vomiting.
Rinse mouth with water.
Get immediate medical help—carbon disulfide is highly toxic if ingested.
FIRE FIGHTING MEASURES
Flammability:
Extremely flammable—vapors can form explosive mixtures with air.
Ignites readily at room temperature.
Extinguishing Media:
Use foam, dry chemicals, or carbon dioxide (COâ‚‚).
