Sodium gentisate, with the CAS number 4955-90-2, is a chemical compound that is of great significance in various industries. Chemically, it is the sodium salt of gentisic acid. The molecular formula of sodium gentisate is C7H5NaO4, and its molecular weight is approximately 176.10 g/mol. It usually appears as a white to off - white powder.
This compound has good solubility characteristics. It is soluble in water, which makes it convenient for a variety of applications where an aqueous solution is required. The purity of the factory - supplied sodium gentisate is carefully controlled to meet high - quality standards, ensuring its effectiveness in different uses.
**Pharmaceutical Industry**: Sodium gentisate has shown potential in the pharmaceutical field. It has anti - inflammatory and antioxidant properties. It can be used in the development of drugs for the treatment of certain inflammatory diseases. For example, it may help in reducing inflammation associated with arthritis by inhibiting the production of inflammatory mediators in the body.
**Cosmetics Industry**: Due to its antioxidant effects, it is incorporated into skincare products. It can protect the skin from oxidative stress caused by environmental factors such as UV radiation and pollution. This helps in preventing premature aging, reducing the appearance of fine lines and wrinkles, and keeping the skin healthy and youthful.
**Chemical Research**: It serves as an important intermediate in organic synthesis. Chemists use it to synthesize more complex chemical compounds with specific properties for use in various research and industrial applications.
**In Pharmaceutical Applications**: When used in pharmaceutical formulations, the dosage and method of use are strictly regulated. It is usually formulated into tablets, capsules, or injections under the guidance of pharmaceutical experts. The dosage depends on the specific disease being treated, the patient's age, weight, and overall health condition. For example, in the treatment of mild inflammatory conditions, a lower dosage may be initially prescribed, and the dosage may be adjusted based on the patient's response.
**In Cosmetics**: In skincare products, it is added to creams, lotions, and serums. The concentration of sodium gentisate in cosmetics typically ranges from 0.5% to 5%. Before applying a product containing sodium gentisate to the entire face or body, it is recommended to perform a patch test on a small area of the skin to check for any allergic reactions.
**In Chemical Research**: In a laboratory setting, it should be handled with proper safety precautions. Appropriate protective equipment such as gloves and goggles should be worn. It is usually dissolved in a suitable solvent according to the specific reaction requirements. The reaction conditions, including temperature, pressure, and reaction time, should be carefully controlled to ensure the success of the synthesis.
**Pharmaceutical Case**: A clinical trial was conducted on a group of patients with mild to moderate arthritis. The patients were divided into two groups: one group received a drug containing sodium gentisate, and the other group received a placebo. After 12 weeks of treatment, the group using the sodium gentisate - containing drug showed a significant reduction in joint pain and inflammation compared to the placebo group. The patients reported improved mobility and a better quality of life.
**Cosmetics Case**: A skincare brand launched a new anti - aging serum containing 2% sodium gentisate. After a 3 - month consumer trial, 80% of the participants reported a visible reduction in the appearance of fine lines and wrinkles. Their skin also felt more hydrated and looked brighter.
**Chemical Research Case**: In a chemical research project, sodium gentisate was used as an intermediate to synthesize a new type of fluorescent compound. By carefully controlling the reaction conditions, the researchers were able to obtain the desired compound with high yield and purity. This new fluorescent compound has potential applications in biological imaging and sensor technology.
