1,10-phenanthroline

1,10-phenanthroline is an organic nitrogen-containing heterocyclic compound with the molecular formula C12H8N2 and CAS number 66-71-7. This white to pale yellow crystalline solid belongs to the phenanthroline family and serves as a bidentate chelating ligand. With a molecular weight of 180.2 g/mol, it forms stable complexes with various metal ions, making it valuable in analytical chemistry and coordination chemistry applications.

1,10-phenanthroline appears as white to pale yellow crystalline needles or powder at room temperature. It has a molecular weight of 180.2 g/mol and melts at approximately 117°C. The compound is sparingly soluble in water but readily dissolves in organic solvents like ethanol and acetone. It exhibits excellent chelating properties due to its two nitrogen atoms positioned to form five-membered rings with metal ions.

1,10-phenanthroline serves primarily as a chelating agent and analytical reagent in laboratory applications. It is widely used for the spectrophotometric determination of iron, forming an orange-red complex with Fe(II). The compound also finds applications in coordination chemistry research, as a ligand in metal complex synthesis, and in some pharmaceutical intermediates. Its strong metal-binding properties make it valuable in various analytical procedures.

1,10-phenanthroline requires careful handling due to its Acute Tox. 3 classification and 'Danger' signal word. Always wear appropriate personal protective equipment including safety glasses, gloves, and lab coats. Work in well-ventilated areas or under fume hoods to avoid inhalation. Prevent skin and eye contact, and avoid ingestion. The compound displays GHS06 (skull and crossbones) and GHS09 (environmental hazard) pictograms, indicating both toxicity and environmental concerns.

1,10-phenanthroline should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep the substance away from incompatible materials and ensure proper labeling according to CLP regulations. Due to its environmental hazard classification (Aquatic Acute 1, Aquatic Chronic 1), implement measures to prevent environmental release. Store in original containers and maintain inventory records for regulatory compliance.

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

1,10-phenanthroline waste must be disposed of according to local, national, and international regulations due to its toxic and environmentally hazardous properties. Contact licensed waste disposal companies for proper treatment and disposal. Do not discharge into sewers, waterways, or soil due to its aquatic toxicity classification. Collect waste in appropriate containers, label clearly, and maintain disposal records. Consider recovery or recycling options where available and economically feasible.

1,10-phenanthroline is classified under ADR as Class 6.1 (toxic substances), Packing Group III, indicating moderate toxicity during transport. It must be packaged in UN-approved containers with appropriate hazard labels and documentation. Transport vehicles must comply with ADR requirements for Class 6.1 substances. Ensure proper documentation including transport documents, safety data sheets, and emergency response information accompanies shipments throughout the European transport network.

1,10-phenanthroline is subject to various European chemical regulations including REACH registration requirements and CLP classification obligations. It is not currently listed as an SVHC (Substance of Very High Concern). Companies must comply with safety data sheet requirements, proper labeling with GHS pictograms, and workplace exposure limits. Environmental regulations may apply due to its aquatic toxicity classification, requiring appropriate risk management measures and environmental monitoring.
