Benzoic acid, also known as benzoic acid, is an aromatic acid that has antibacterial activity when not dissociated. Sodium benzoate is a sodium salt of benzoate, which has no odor or a slightly soothing aroma. It can be partially converted into active benzoic acid in acidic substances, and its anti-corrosion mechanism is the same as benzoic acid. Due to its greater solubility in water and stability in air, sodium benzoate has a stronger inhibitory effect on yeast and bacteria, making it more commonly used than benzoic acid. Benzoic acid and sodium benzoate are widely used as food preservatives and are also one of the commonly used preservatives for oral liquid medicine. Studies have shown that benzoic acid and sodium benzoate are often abused by unscrupulous manufacturers in food and medicine due to their low cost. Therefore, excessive intake of benzoic acid and sodium benzoate during consumption is inevitable, which can be harmful to the human liver and even carcinogenic. At present, ...

Sodium cyclamate, a commonly used artificial sweetener. Sodium cyclamate, also known as cyclamic acid sodium salt, is used as a sugar substitute in various food and beverage products. Here are some key points about sodium cyclamate: Sweetness: Sodium cyclamate is approximately 30 to 50 times sweeter than sugar (sucrose). Its intense sweetness allows for small quantities to be used to achieve the desired level of sweetness in food and drinks. Low Calorie: Like other artificial sweeteners, sodium cyclamate is low in calories. It provides sweetness to food and beverages without significantly contributing to caloric intake. This makes it a popular choice for individuals who want to reduce their sugar consumption or manage their calorie intake. Stability: Sodium cyclamate is stable under normal storage and cooking conditions. It withstands high temperatures, making it suitable for use in products that require heat processing or baking. Regulatory Approval: Sodium cyclamate ha...

    Medical grade vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin. Vitamin C can participate in amino acid metabolism, neurotransmitter synthesis, collagen and tissue cell matrix synthesis, reduce capillary permeability, accelerate blood coagulation, stimulate coagulation function, promote iron absorption in the intestine, promote blood lipid lowering, increase the body's resistance to infection, participate in detoxification function, and have anti histamine effects and prevent the generation of carcinogens (nitrosamines). It can be used as an auxiliary treatment for the prevention and treatment of scurvy, various acute and chronic infectious diseases, and purpura. High dose intravenous injection is used for timely rescue of Keshan syndrome and cardiogenic shock. It can also be used for the treatment of chronic iron poisoning and idiopathic methemoglobinopathy.      Vitamin C is a strong antioxidant that can directly interact wit...

Disodium dihydrogen pyrophosphate appears as a white monoclinic, crystalline powder with a relative density of 1.862. When heated above 220 ℃, it decomposes into sodium metaphosphate. Easy to dissolve in water, insoluble in ethanol. When heated in acidic media, it hydrolyzes into orthophosphate, which has hygroscopicity. After absorbing water, it forms hexahydrate crystals. It can form chelates with Cu2+and Fe2+, and the aqueous solution is hydrolyzed into phosphoric acid by heating with dilute sulfuric acid and inorganic acid. APPLICATIONCan be used as a functional water retention agent, pH regulator, and metal chelating agent. This product is an acidic salt and is generally not used alone. Often mixed with sodium pyronate (an alkaline salt that has a specific effect on proteins in meat and can significantly enhance its water holding capacity). This product reacts with sodium bicarbonate to generate carbon dioxide and can be used as a raw material for rapid fermentation powder. In the...

Welcome to this science blog. The compound we're going to talk about today is benzoic acid. Benzoic acid is an organic compound belonging to the carboxylic acid family with the formula C6H5COOH and the structural formula C6H5-COOH.First, let's look at the properties of benzoic acid. Benzoic acid is a colorless crystalline solid with a special aromatic taste. It is soluble in water at room temperature, but has a low solubility in cold water. Benzoic acid is an acidic compound that reacts with a base to form a corresponding salt, such as sodium benzoate.Benzoic acid is widely used in chemical industry and biological science. Let's take a look at some of its important application areas:Chemical industry: Benzoic acid is widely used as a raw material and intermediate in organic synthesis. It can be used to synthesize dyes, fragrances, drugs, pesticides and other chemicals. In addition, benzoic acid is also one of the important raw materials for preparing polystyrene.Pharmaceutical field: B...

Aspirin: The Wonder Drug with Multiple BenefitsIntroduction:Aspir, also known as acetylsicylic acid, a widely recognized and widely used medication that has been around for over a century. It is one of the versatile drugs available, with a multitude of applications in various medical conditions. In this blog, we will explore the history, mechanism of action, and the diverse uses of aspirin.A Brief History:Aspirin's story begins in the late 19th century when a German chemist named Felix Hoffmann synthesized acetylsalicylic acid as a painkiller for his father's rheumatism. The drug was later refined and marketed by the pharmaceutical company Bayer, gaining immense popularity worldwide.Mechanism of Action:Aspirin belongs to a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). It works by inhibiting the production of certain chemicals in the body called prostaglandins. Prostaglandins are responsible for causing inflammation, pain, and fever. By reducing their production, ...
