Product Description
1,6-Dibromopyrene (CAS: 27973-29-1) is a high-purity polycyclic aromatic hydrocarbon (PAH) derivative, featuring two bromine substituents at the 1- and 6-positions of the pyrene ring. It appears as a yellow to orange crystalline powder, with high chemical stability and good solubility in organic solvents. Synthesized mainly via direct bromination of pyrene, it is a key intermediate for organic electronics, optoelectronic materials, and fine chemical synthesis.
Uses

Physical & Chemical Properties
- Appearance: Yellow to orange crystalline powder; odorless; no visible impurities.
- Melting Point: 228–232°C (lit.); Boiling Point: 487.1±25.0°C (predicted); Density: 1.846±0.06 g/cm3 (25°C, predicted); Flash Point: 248.4±23.2°C (predicted).
- Solubility: Insoluble in water; soluble in chloroform, dichloromethane, toluene, and other organic solvents; slightly soluble in ethanol and acetone.
- Stability: Stable under normal temperature and pressure; incompatible with strong oxidizing agents; avoid prolonged exposure to high temperature (>200°C) and direct sunlight.
- Toxicity & Safety: Possible chronic toxicity (PAH derivative); irritating to skin and eyes; no detailed acute toxicity data; handle with caution. GHS Labeling: Warning; avoid inhalation and contact.
Synthesis & Storage
- Synthesis: Mainly via direct bromination of pyrene: pyrene reacts with bromine in the presence of a catalyst (such as iron powder) in an organic solvent, followed by filtration, washing, recrystallization, and drying to obtain high-purity 1,6-dibromopyrene.
- Storage: Store at 10–25°C in a cool, dry, well-ventilated, dark warehouse; keep in sealed containers under inert atmosphere to prevent oxidation and moisture absorption. Packed in 1kg, 5kg, or 25kg sealed plastic drums. Avoid direct sunlight, high temperature (>30°C), and contact with strong oxidants; keep away from food and feed. Shelf life: 24 months if unopened and stored properly.
- Handling Precautions: Use in well-ventilated areas; wear dust mask, nitrile gloves, and safety goggles. Avoid skin, eye contact, and inhalation of dust. In case of contact, rinse thoroughly with water. Dispose of waste in accordance with local regulations.
