2-Nitro-5-chloroaniline
Overview
2-Nitro-5-chloroaniline is an organic compound widely used as an intermediate in the synthesis of dyes and pigments. Its molecular structure consists of a benzene ring substituted with a nitro group and a chlorine atom, which contribute to its reactivity and utility in industrial applications. The compound is typically produced through nitration and chlorination processes, resulting in a yellow to orange crystalline powder. Industrial-grade 2-Nitro-5-chloroaniline is favored for its cost-effectiveness and consistent performance in chemical manufacturing.
Physical and Chemical Properties
2-Nitro-5-chloroaniline exhibits moderate solubility in common organic solvents such as ethanol and acetone, but it is only slightly soluble in water. The compound has a melting point range of 100-104°C, making it stable under typical storage conditions. Chemically, it is relatively stable but can decompose when exposed to high temperatures or strong acids and bases. The presence of both nitro and chloro substituents enhances its reactivity, making it a versatile building block in organic synthesis.
Main Applications
The primary use of 2-Nitro-5-chloroaniline is in the production of dyes and pigments, particularly azo dyes, which are widely used in textiles, plastics, and inks. Its ability to form stable intermediates makes it valuable in chemical synthesis. Additionally, it serves as a precursor in the manufacture of pharmaceuticals and agrochemicals, though its use in these fields is less common compared to dye production.
Safety and Storage
Handling 2-Nitro-5-chloroaniline requires caution due to its potential health hazards. It is harmful if ingested or inhaled and may cause skin and eye irritation. Proper personal protective equipment (PPE), including gloves and goggles, should be used. Storage should be in a cool, dry, and well-ventilated area, away from direct sunlight and moisture. Containers must be tightly sealed to prevent contamination and degradation.
B2B Procurement Guide
When procuring 2-Nitro-5-chloroaniline, buyers should prioritize suppliers with certifications such as ISO or GMP to ensure product quality. Key specifications to verify include purity levels (typically 98% or higher for industrial use) and CAS number authenticity. Price negotiations should consider bulk purchase discounts, but buyers should also factor in logistics and storage costs. Reliable suppliers often provide technical support and safety data sheets (SDS) for regulatory compliance.
