Thiophene CAS 110-02-1

1. Thiophene is a fundamental heterocyclic compound and a versatile building block in organic synthesis, used as a non-polar solvent and a key intermediate for producing dyes and pharmaceuticals . Its derivatives are essential in modern material sciences for creating organic semiconductors, nonlinear optics, solar cells, and sensors .
2. The compound serves as a crucial C4-building block for constructing complex ring systems found in biologically active natural products and pharmaceutical agents .Thiophene CAS 110-02-1 can undergo reactions like dearomative cycloadditions to form highly substituted benzenes, important for drug discovery and crop science .
3. Applications of Thiophene also include its presence as a secondary metabolite in plants and microbes , its use in agricultural chemicals with pesticidal activity , and as a precursor for thiophene S-oxides and S,S-dioxides used in cascade reactions to create complex molecular frameworks .

1. Store Thiophene in a tightly sealed container under an inert gas (e.g., nitrogen) in a cool, dry, well-ventilated area, protected from light and heat . Recommended storage is in a cool and dark place below 15°C .
2. Keep Thiophene strictly away from strong oxidizing agents (including concentrated nitric acid) and ignition sources (heat, sparks, open flames), as Thiophene CAS 110-02-1 is highly flammable and reacts violently with oxidizers, creating fire and explosion hazards .
3. Always use appropriate personal protective equipment (PPE) including chemical-resistant gloves (e.g., rubber), safety goggles with face protection, and anti-static protective clothing; use only with explosion-proof equipment and adequate ventilation in a fume hood.

1. Immediately isolate the spill area (at least 50 meters/150 feet in all directions) and eliminate all ignition sources . For large spills, consider initial downwind evacuation for at least 300 meters (1000 feet) .
2. Contain Thiophene using dry, inert, non-combustible absorbent material (e.g., dry sand) and DO NOT touch or walk through spilled material . Carefully collect using non-sparking tools into sealed, labeled chemical waste containers for proper disposal according to local, state, and federal environmental regulations .
3. Personnel Thiophene CAS 110-02-1 must wear full chemical-protective equipment including positive pressure self-contained breathing apparatus (SCBA) during cleanup . Prevent entry into drains or waterways as Thiophene is harmful to aquatic life . Thiophene is classified for transport (UN2414, Hazard Class 3, PG II) .

1. Thiophene is classified with GHS signal word "Danger" and is a highly flammable liquid and vapor (H225) with a flash point ranging from -9°C to -1°C (16-30°F) . Thiophene CAS 110-02-1 causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation .
2. Thiophene is harmful if swallowed (H302) and may cause damage to organs (liver, brain) through prolonged or repeated exposure (H373) . It is harmful to aquatic life with long-lasting effects (H412) . Vapors are heavier than air (vapor density 2.9) and may form explosive mixtures with air (LEL 2.1%, UEL 17.25%) . Thermal decomposition or combustion produces toxic and irritating fumes including carbon oxides and sulfur oxides .
3. Always consult the specific Safety Data Sheet (SDS) for Thiophene for complete hazard information, first-aid procedures (P305+P351+P338 for eyes, P303+P361+P353 for skin, P301+P330+P331 for ingestion, P304+P340 for inhalation), and handling instructions. Precautionary statements include P210 (keep away from heat/sparks/open flames), P233 (keep container tightly closed), P240 (ground/bond container), and P280 (wear protective gloves/eye protection) .
