Overview
p-Nitrotoluene (PNT) is an organic compound widely used in industrial applications, particularly in the synthesis of dyes, pharmaceuticals, and explosives. Detection of p-nitrotoluene is crucial for quality control, environmental monitoring, and safety compliance in manufacturing processes. The compound is characterized by its yellow crystalline appearance and distinct chemical properties. Due to its toxic and flammable nature, proper detection and handling are essential to prevent health hazards and environmental contamination.
Physical and Chemical Properties
p-Nitrotoluene is a yellow crystalline solid with a molecular weight of 137.14 g/mol. It has a melting point of 51-53°C and a boiling point of 238°C. The compound is slightly soluble in water but dissolves well in organic solvents such as ethanol and ether. Its density is 1.286 g/cm³, and it exhibits toxic and flammable properties. Under certain conditions, p-nitrotoluene can become explosive, necessitating careful handling and storage.
Main Applications
p-Nitrotoluene serves as a key intermediate in the production of various industrial products. It is primarily used in the synthesis of dyes, where it contributes to vibrant color formulations. Additionally, it finds applications in the pharmaceutical industry for drug manufacturing. Another significant use of p-nitrotoluene is in the production of explosives, where its chemical properties are leveraged to create stable and effective compounds. Its role in these industries underscores the importance of accurate detection and quality assurance.
Safety and Storage
Due to its toxic and flammable nature, p-nitrotoluene requires strict safety measures during handling and storage. Workers should use personal protective equipment (PPE), including gloves and goggles, to avoid skin contact and inhalation. Storage conditions should include a cool, dry, and well-ventilated area, away from heat sources and open flames. Proper labeling and segregation from incompatible materials are also critical to prevent accidents and ensure workplace safety.
B2B Procurement Guide
When procuring p-nitrotoluene, buyers should prioritize suppliers who comply with safety and environmental regulations. Verification of the CAS number (99-99-0) and purity specifications is essential to ensure product quality. The reference price range for p-nitrotoluene is approximately $10-$20 per kg, depending on purity and supplier. Bulk purchases may offer cost advantages, but buyers should also consider storage and handling requirements to maintain product integrity.
