109-97-7
Product name: Pyrrole
English alias: Azole; Divinylenimine; 1H-Pyrrole
CAS: 109-97-7
Molecular formula: C4H5N
Appearance: Colorless to pale yellow liquid
Package: 180kg/drum
Pyrrole is a five-membered heterocyclic aromatic compound containing nitrogen. It is a fundamental building block in organic synthesis and biochemistry, serving as the core structure for porphyrins, heme, and chlorophyll. The compound is characterized by its high reactivity and sensitivity to air and light. Its molecular formula is C₄H₅N, and it appears as a colorless to pale yellow liquid with a characteristic chloroform-like odor. It is sparingly soluble in water but miscible with most organic solvents.

Pyrrole is flammable and may form explosive peroxides. It is harmful if swallowed, inhaled, or absorbed through skin. Causes severe skin burns and eye damage. May cause respiratory irritation. Suspected of causing genetic defects. Requires special handling under inert atmosphere. Always use appropriate personal protective equipment and refer to the Safety Data Sheet (SDS).
Store under inert gas (nitrogen/argon) in a cool, ventilated area
Keep containers tightly sealed and protected from light
Regularly test for peroxide formation (every 3 months)
Store away from heat, sparks, and open flames
Use corrosion-resistant storage equipment
Maintain temperature between 2-8°C for long-term storage
Available in 180kg stainless steel drums under nitrogen atmosphere. Classified as flammable liquid (Class 3) and toxic material. UN number: UN1992. Requires hazardous material documentation and special handling. Transport in temperature-controlled vehicles with explosion-proof equipment. Shelf life: 6 months when stored under proper conditions.
