1,10-phenanthroline

1,10-phenanthroline is an organic heterocyclic compound with the molecular formula C12H8N2 and CAS number 66-71-7. This aromatic compound consists of three fused benzene rings with two nitrogen atoms positioned at the 1 and 10 positions. With a molecular weight of 180.2 g/mol, it serves as an important chelating agent and analytical reagent in various chemical applications.

1,10-phenanthroline is a white to pale yellow crystalline solid at room temperature. It exhibits poor solubility in water but dissolves readily in organic solvents such as ethanol and chloroform. The compound is odorless and has a melting point around 117°C. Its planar aromatic structure allows it to form stable complexes with metal ions through coordination bonding.

1,10-phenanthroline is primarily used as a chelating agent and analytical reagent in laboratory settings. It serves as a colorimetric indicator for iron determination, forming distinctive red complexes with Fe2+ ions. The compound is also utilized in coordination chemistry research, as a ligand in metal complex synthesis, and in electrochemical applications. Additionally, it finds use in pharmaceutical research and environmental analysis.

1,10-phenanthroline must be handled with appropriate personal protective equipment due to its Acute Tox. 3 classification. Wear chemical-resistant gloves, safety goggles, and protective clothing when handling. Work in well-ventilated areas or under fume hoods to avoid inhalation. Avoid skin and eye contact, and prevent ingestion. The GHS06 pictogram indicates acute toxicity hazards, requiring careful handling procedures and emergency response preparedness.

1,10-phenanthroline should be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers tightly sealed to prevent moisture absorption and contamination. Store separately from incompatible materials such as strong oxidizing agents. Maintain storage temperatures below 25°C and ensure proper labeling with hazard information. Regular inventory checks should be conducted to monitor container integrity.

In case of skin contact with 1,10-phenanthroline, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention.

1,10-phenanthroline waste must be disposed of according to local and national hazardous waste regulations due to its toxicity and environmental hazard classification. Contact licensed hazardous waste disposal companies for proper treatment. Do not discharge into drains, soil, or water bodies as it poses risks to aquatic environments (Aquatic Acute 1, Aquatic Chronic 1). Maintain proper waste documentation and follow facility-specific disposal protocols.

1,10-phenanthroline is classified as ADR Class 6.1 (toxic substances), Packing Group III for transportation purposes. It requires appropriate UN specification packaging and hazard labeling during transport. Shipping documentation must include proper shipping names, hazard classes, and emergency contact information. Transport vehicles must carry appropriate emergency equipment and drivers need ADR training certification for toxic substance transport.

1,10-phenanthroline is subject to CLP regulation requirements for classification, labeling, and packaging due to its hazardous properties. It falls under REACH registration obligations for importers and manufacturers. While not currently listed as an SVHC substance, its acute toxicity and environmental hazard classifications require compliance with occupational safety regulations and environmental protection measures across EU member states.
