Product Name: 2-Aminoterephthalic acid
Molecular Formula: C8H7NO4
Molecular Weight: 181.15
Appearance: Usually a white to light - yellow crystalline powder.
Solubility: Slightly soluble in water and soluble in some organic solvents such as dimethyl sulfoxide (DMSO).
Melting Point: Approximately 320 - 330 °C (decomposition).
Uses
Intermediate in Organic Synthesis: In drug synthesis, it can be used to construct the molecular structure of drugs with specific pharmacological activities. In dye synthesis, it serves as an important raw material for synthesizing dyes with special colors and properties.
Materials Science Field: It is used to prepare high - performance polymer materials such as polyamides and polyesters. By introducing functional groups such as amino and carboxyl groups, the properties of the materials can be improved, such as enhancing the material's strength, heat resistance, and chemical corrosion resistance. In addition, it can be used to prepare metal - organic framework materials (MOFs), which have broad application prospects in the fields of gas adsorption, separation, and catalysis.
Preparation Methods
Using terephthalic acid as the raw material, a nitro group is introduced onto the benzene ring through a nitration reaction, and then the nitro group is converted into an amino group through a reduction reaction to obtain 2 - aminoterephthalic acid. The specific reaction conditions and reagent selection will vary depending on the process route. For example, in the nitration reaction, a mixed acid of concentrated nitric acid and concentrated sulfuric acid can be used as the nitrating reagent, and the reaction is carried out at an appropriate temperature. In the reduction reaction, metals such as iron powder and zinc powder can be used to reduce the nitro group under acidic conditions, or the catalytic hydrogenation method can be used for reduction.
Precautions
Irritation: It is irritating to the eyes, skin, and respiratory tract. Contact may cause redness, pain, allergies, and other symptoms. During use, direct contact with the skin and eyes should be avoided. In case of contact, rinse immediately with plenty of water and seek medical attention promptly.
Storage Conditions: It should be stored in a cool, dry, and well - ventilated warehouse, away from fire sources and heat sources, and protected from direct sunlight. At the same time, it should be stored separately from oxidants, acids, alkalis, etc. to avoid mixing storage and chemical reactions.
