Industrial Grade 99% Para Aminophenol (4-Aminophenol) Pharmaceutical & Dye Intermediate CAS 123-30-8 for Paracetamol Production

Para Aminophenol (4-Aminophenol, PAP, CAS:123-30-8,EINECS:204-616-2, HS Code:2922299090, molecular formula C₆H₇NO, MW:109.13) is a white crystalline powder produced via advanced nitrobenzene catalytic hydrogenation or p-nitrophenol reduction followed by purification and crystallization processes. Our industrial grade PAP features 99.0% minimum purity with ultra-low impurity content, offering moderate water solubility (1.5g/100mL at 20°C) and forming a weakly acidic solution. With a melting point of 186-189°C and flash point of 189°C, it is a stable intermediate widely used in pharmaceutical and dye industries. As a critical building block, it serves as the primary raw material for paracetamol (acetaminophen) production, a globally used analgesic and antipyretic drug. Our product strictly adheres to industrial standards with consistent quality and reliable performance for various fine chemical applications.

Applications
Pharmaceutical Intermediate (Core Application: Paracetamol Production)
Primary raw material for synthesizing paracetamol (acetaminophen), the world's most widely used over-the-counter analgesic and antipyretic drug. It also serves as an intermediate for other pharmaceuticals including:
Acebutolol (beta-blocker for hypertension treatment)
Ambroxol (mucolytic agent for respiratory diseases)
Sorafenib (anticancer drug for liver and kidney cancer)
Other APIs requiring aromatic amine and phenol functional groups
Dye & Pigment Manufacturing
Key intermediate for producing:
Sulfur dyes (e.g., Sulfur Blue FBG, Weak Acid Brilliant Yellow 5G)
Azo dyes and pigments for textiles, leather, and paper industries
Hair dyes and fur coloring agents
Photographic Chemicals
Precursor for manufacturing black-and-white photographic developers (e.g., N-methyl-p-aminophenol) and antioxidants for film preservation.
Rubber & Polymer Additives
Used in producing antioxidants, antiozonants, and stabilizers for rubber and polymer materials, including:
4-Hydroxydiphenylamine (polymer stabilizer)
N,N'-Diphenyl-1,4-phenylenediamine (rubber antioxidant)
Analytical Reagents & Fine Chemicals
Applied as a reagent in analytical chemistry and as a building block for synthesizing specialty chemicals, corrosion inhibitors, and UV stabilizers.

Packaging & Storage
Standard packaging: 25kg UN certified fiber drums with PE liners, 50kg HDPE drums, or 1000kg FIBC bulk bags with moisture barriers. Store in a cool (≤25°C), dry, well-ventilated warehouse away from direct sunlight, moisture, and incompatible substances (oxidizing agents, strong acids, food/feed products). Keep containers tightly sealed to prevent moisture absorption and discoloration (turns violet on light exposure). Shelf life is 24 months under recommended storage conditions when properly sealed and protected from light.

Safety Information
Classified as UN 2512, Class 6.1 (Toxic Substances), Packing Group III for international transportation. Harmful if swallowed, inhaled, or absorbed through skin; may cause skin irritation, eye damage, and allergic reactions. Operators must wear chemical-resistant gloves, splash-proof goggles, and protective clothing during handling. In case of skin/eye contact, flush with copious amounts of water for at least 15 minutes; seek medical attention immediately if irritation persists. All transportation complies with IMDG/IATA/ADR regulations; complete MSDS with emergency response procedures is provided with each shipment.
