Salicylamide, with the CAS number 65 - 45 - 2, is a white to off - white crystalline powder. It has a molecular formula of C₇H₇NO₂ and a molecular weight of 137.14 g/mol. The melting point of salicylamide ranges from 138 - 142°C. It is sparingly soluble in water but soluble in alcohol, ether, and chloroform. High - quality salicylamide of this kind is available at a good price, meeting the requirements of various industries. The product is produced under strict quality control, ensuring high purity and stability.
1. **Pharmaceutical Industry**: Salicylamide is commonly used as an analgesic and antipyretic agent. It can relieve mild to moderate pain, such as headache, toothache, and muscle pain. It also helps in reducing fever by affecting the hypothalamus in the brain to regulate body temperature.
2. **Intermediate in Chemical Synthesis**: It serves as an important intermediate in the synthesis of various other chemicals. For example, it can be used in the production of dyes, pesticides, and other pharmaceutical compounds.
3. **Research**: In scientific research, salicylamide can be used as a reference standard or a research reagent to study its biological activities, chemical reactions, and interactions with other substances.
1. **Pharmaceutical Use**: When used as a pharmaceutical, the dosage should be determined according to the patient's age, weight, and the severity of the condition. Generally, for adults, the recommended oral dose is 0.3 - 1 g per time, 3 - 4 times a day. It should be taken with plenty of water to ensure proper absorption.
2. **Chemical Synthesis**: In chemical synthesis, the amount of salicylamide used depends on the specific reaction and the desired yield. It should be added carefully to the reaction system under appropriate conditions, such as temperature, pressure, and solvent selection.
3. **Research Use**: In the laboratory, the usage of salicylamide should follow the experimental protocol. It may need to be dissolved in a suitable solvent and then added to the reaction or test system.
1. **Pain Relief in a Hospital Setting**: A patient came to the hospital complaining of a severe headache. After a doctor's diagnosis, salicylamide was prescribed. The patient took 0.5 g of salicylamide orally. Within half an hour, the headache was significantly relieved, and the patient's condition gradually improved.
2. **Chemical Synthesis in a Laboratory**: A research team was synthesizing a new type of dye. They used salicylamide as an intermediate. By carefully controlling the reaction conditions, such as reacting at a temperature of 80°C in an ethanol - water solvent system for 5 hours, they successfully obtained a high - yield and high - quality dye product.
3. **Research on Biological Activity**: A group of scientists was studying the anti - inflammatory effect of salicylamide. They prepared cell models and added different concentrations of salicylamide to the cell cultures. Through a series of experiments, they found that salicylamide could inhibit the production of certain inflammatory cytokines, indicating its potential anti - inflammatory activity.
