P aminophenol price

When sourcing P-Aminophenol (PAP), the price is heavily dictated by purity levels (typically ≥99% or ≥99.5%) and the physical form (crystalline powder vs. granules). For pharmaceutical applications, such as the synthesis of Paracetamol, you must ensure low ash content (<0.1%) and minimal iron content (<10ppm) to prevent discoloration. Always request a Certificate of Analysis (COA) to verify the melting point (186-189°C) and moisture content, as these directly impact the yield in chemical synthesis.

The end-use significantly affects the compliance standards. For Pharmaceutical Grade, suppliers must adhere to GMP (Good Manufacturing Practice) and often provide DMF (Drug Master File) documentation. For Industrial/Dye Grade used in hair dyes or rubber antioxidants, the focus shifts to color stability and solubility. Buyers should specify the application to the supplier to ensure the particle size distribution and packaging (typically 25kg fiber drums or 500kg big bags) align with their production line requirements.

As a chemical intermediate, P-Aminophenol must comply with REACH regulations for the European market and TSCA for the US. It is classified under UN Number 2512 (Class 6.1 toxic substances) for international transport. Ensure the supplier provides a comprehensive Safety Data Sheet (SDS/MSDS) that meets GHS (Globally Harmonized System) standards. Verification of ISO 14001 (Environmental Management) is also recommended, as PAP production involves significant wastewater treatment considerations.

The price of P-Aminophenol is sensitive to the cost of raw materials like Nitrobenzene and environmental regulation shifts in manufacturing hubs. To mitigate risk, consider long-term framework agreements with price adjustment clauses or bulk purchasing during off-peak seasons. On Made-in-China.com, you can identify Audited Suppliers who offer stable pricing structures and have the capacity to buffer against short-term market fluctuations.

Since PAP is a Class 6.1 hazardous material, it requires specialized dangerous goods (DG) packaging and labeling. Ensure your freight forwarder is experienced in handling IMO Class 6.1 sea freight. You must confirm that the supplier provides U.N. certified packaging to prevent leakage and oxidation (turning brown/purple upon exposure to air), which can degrade the product quality during long-distance cross-border transit.

Always utilize Secure Payment services or Letters of Credit (L/C) for large-scale chemical orders to protect your capital. To ensure quality consistency, mandate a pre-shipment inspection (PSI) by third parties like SGS or Intertek. This inspection should include random sampling and lab testing to confirm the batch matches the approved sample before the final balance is paid.
