Overview
3-Aminophenol, also known as meta-aminophenol, is an organic compound belonging to the class of aromatic amines. It is a white to light brown crystalline powder with a faint aromatic odor. The compound is primarily used as an intermediate in the synthesis of dyes, pharmaceuticals, and photographic chemicals. Its chemical structure consists of a phenol group with an amino group at the meta position, making it a versatile building block in organic chemistry. 3-Aminophenol is produced through the reduction of 3-nitrophenol or other synthetic routes. It is commercially available in various purity grades, with industrial-grade and pharmaceutical-grade being the most common. The compound is sensitive to oxidation and should be handled with care to prevent degradation.
Physical and Chemical Properties
3-Aminophenol exhibits typical properties of an aromatic amine. It has a molecular weight of 109.13 g/mol and a density of 1.15 g/cm³. The compound melts at 122-124°C and boils at 164°C under reduced pressure (11 mmHg). It is soluble in water, ethanol, and ether, making it suitable for various chemical reactions and formulations. The compound is a weak base and can form salts with acids. It is sensitive to light and air, which can cause oxidation and discoloration. Proper storage conditions, such as cool, dry, and well-ventilated areas, are essential to maintain its stability. 3-Aminophenol is also known for its ability to undergo diazotization and coupling reactions, which are crucial in dye synthesis.
Main Applications
3-Aminophenol is a key intermediate in the production of azo dyes, which are widely used in textiles, inks, and plastics. Its ability to form diazonium salts makes it valuable in creating vibrant and durable colorants. In the pharmaceutical industry, it serves as a precursor for drugs such as paracetamol and other analgesics. The compound is also used in the photographic industry as a developer agent, where it helps in the reduction of silver halides to form images. Additionally, 3-aminophenol is employed in hair dye formulations due to its ability to produce long-lasting and intense colors. Its versatility and reactivity make it indispensable in various chemical manufacturing processes.
Safety and Storage
3-Aminophenol is classified as harmful if swallowed and can cause skin and eye irritation. Proper personal protective equipment (PPE), including gloves, goggles, and lab coats, should be worn when handling the compound. Inhalation of dust or vapors should be avoided, and work should be conducted in a well-ventilated area or under a fume hood. Storage conditions are critical to maintaining the compound's stability. It should be kept in a cool, dry place away from light and moisture. Containers should be tightly sealed to prevent exposure to air, which can lead to oxidation. In case of spills, the affected area should be cleaned immediately using appropriate absorbent materials and disposed of according to local regulations.
B2B Procurement Guide
When procuring 3-aminophenol, B2B buyers should verify the CAS number (591-27-5) and the purity grade required for their specific application. Industrial-grade purity (98-99%) is suitable for most chemical syntheses, while pharmaceutical-grade (≥99.5%) is necessary for drug manufacturing. It is advisable to request certificates of analysis (CoA) and material safety data sheets (MSDS) from suppliers. Packaging options typically include 25 kg fiber drums or custom quantities based on buyer needs. Buyers should also consider the supplier's reputation, production capacity, and compliance with international standards such as ISO or GMP. For reference, the price ranges from approximately $10 to $20 per kg, depending on purity and order volume. Bulk purchases may qualify for discounts.
