Aniline, chemically known as phenylamine or aminobenzene with the CAS number 62-53-3, stands as a pivotal organic compound in the global chemical industry. Its significance lies primarily in its role as a versatile intermediate, forming the backbone for a vast array of downstream products that touch nearly every aspect of modern life. For B2B procurement managers and R&D scientists, understanding the properties and supply chain of Aniline is crucial for ensuring consistent production and cost-effectiveness.

The Chemical Profile of Aniline

Aniline is an aromatic amine, characterized by its colorless to yellowish, oily liquid appearance, though it tends to darken upon exposure to air. Its molecular formula, C6H7N, hints at its structural simplicity yet profound chemical reactivity. With a purity often exceeding 99.95% in industrial grades, it is a highly sought-after raw material. Its relatively low freezing point of -6.4°C and boiling point of 184.13°C make it manageable under standard industrial conditions.

Key Applications Driving Demand for Aniline

The demand for Aniline is predominantly driven by its extensive use as a precursor in several major industries:

  1. Polyurethane Production: The largest single application of Aniline is in the synthesis of methylene diphenyl diisocyanate (MDI). MDI is a critical component in the production of polyurethanes, which are used in everything from rigid and flexible foams for insulation and furniture to coatings, adhesives, and elastomers. Manufacturers relying on polyurethane components find a dependable Aniline supplier for their MDI precursors essential.
  2. Dyes and Pigments: Aniline is historically and currently a foundational intermediate for a wide spectrum of dyes. It is famously used in the production of indigo, the iconic blue dye for denim. Beyond indigo, Aniline derivatives are crucial for creating vibrant pigments used in textiles, paints, inks, and plastics. For companies in the dye manufacturing sector, sourcing high-purity Aniline for dye and pigment manufacturing is a top priority.
  3. Rubber Processing Chemicals: Aniline derivatives, such as phenylenediamines and diphenylamine, act as effective antioxidants and accelerators in the rubber industry. These additives enhance the lifespan and performance characteristics of rubber products, from tires to industrial hoses. Procurement of Aniline for these specialized rubber chemicals is a consistent market need.
  4. Agrochemicals and Pharmaceuticals: Aniline also plays a significant role in the agricultural sector as an intermediate in the synthesis of various herbicides. Furthermore, it is a key building block for several pharmaceuticals, most notably paracetamol (acetaminophen), a common over-the-counter pain reliever and fever reducer. Businesses in the agrochemical and pharmaceutical sectors seek reliable aniline manufacturer for herbicides and drug synthesis.
  5. Other Applications: Aniline is also used in smaller volumes for producing polymers like polyaniline (a conducting polymer), as well as in certain specialty chemicals and research applications.

Sourcing Aniline: Considerations for Procurement Managers

When looking to buy Aniline in bulk, several factors are paramount for industrial purchasers. Purity is critical; variations can significantly impact reaction yields and the quality of the final product. Reliability of supply is another key concern, ensuring uninterrupted production schedules. For many businesses, competitive pricing from a reputable Aniline manufacturer in China offers a significant advantage in managing production costs. Understanding the global Aniline market and its price dynamics is also essential for strategic procurement.
