Product Description

Product Introduction

2-Nitrophenol (CAS 88-75-5), commonly referred to as o-Nitrophenol, is an organic compound with the molecular formula C6H5NO3. It typically appears as light yellow needle-like crystals or a crystalline powder with a characteristic phenolic odor. A unique physical property of 2-Nitrophenol (CAS 88-75-5) is its high steam volatility, which allows for efficient separation from its para-isomer during industrial production. As a versatile aromatic intermediate, it is indispensable in the fine chemical industry for the manufacture of dyes, pesticides, and active pharmaceutical ingredients (APIs).

Product Selling Points

  • Exceptional Purity (≥ 99.5%): Chemfine utilizes advanced distillation and crystallization techniques to ensure minimal levels of 4-nitrophenol and other impurities.

  • Superior Reactivity: Easily reduced to o-aminophenol, serving as a high-quality precursor for downstream pharmaceutical and dye synthesis.

  • Low Moisture Content (≤ 0.1%): Strictly controlled moisture levels ensure stability and prevent side reactions in sensitive organic processes.

  • Steam Volatility Advantage: Excellent volatility characteristics facilitate high-purity extraction and purification in large-scale manufacturing.

  • Consistent Bulk Supply: Large-scale production capacity ensures batch-to-batch stability and long-term supply security for major industrial contracts.

  • Global Safety Compliance: Shipped with full GHS-compliant documentation and UN-certified packaging for international hazardous material transport.


Applications

Dye and Pigment Synthesis Acts as a core intermediate in the production of azo dyes, acid dyes, and various organic pigments used extensively in the textile and coatings industries.

Pharmaceutical Intermediates Primary raw material for the reduction-based synthesis of o-aminophenol, which is further processed into analgesics, anti-inflammatory drugs, and medical contrast agents.

Agricultural Chemicals Integrated into the synthesis of high-efficiency fungicides, insecticides, and plant growth regulators essential for modern crop protection.

Rubber Antioxidants Used to manufacture specialty rubber additives that significantly improve the oxidative resistance and service life of high-performance rubber products.

Chemical Indicators and Reagents Utilized as a pH indicator in laboratory analysis and as a standard reference material in specialized chemical research.


Packaging

Standard industrial packaging options for 2-Nitrophenol include:

  • 25kg fiber drums with double-layer PE moisture-proof inner bags (Standard export packaging).

  • 500kg or 1000kg bulk bags (Jumbo bags) for high-volume automated manufacturing.

  • All packaging is strictly labeled as Class 6.1 (Toxic) in compliance with international maritime and air transport regulations.


Storage

2-Nitrophenol is toxic and slightly volatile. It must be stored in a cool, dry, and well-ventilated dedicated warehouse. Keep containers tightly sealed to prevent dust dispersion and moisture absorption. Store in a dedicated area for toxic substances, away from strong bases, oxidizing agents, and food/feed products. Protect from direct sunlight and high temperatures. Properly stored, it has a shelf life of 24 months.
