Soy Isoflavone CAS NO.: 574-12-9
Molecular structure:
Description:
In soy isoflavones, only aglycone, namely free aglycone, has the highest biological activity. Conjugated glycosides in soy isoflavones can be hydrolyzed to remove malonyl and acetyl groups under heat and alkaline conditions to convert into glucosides. The pH value of alkaline hydrolysis conditions is 8-13, and the degree of hydrolysis increases with the increase of pH value and temperature. The glucosides in soybean isoflavones can be hydrolyzed to remove the glucosyl group in the presence of strong acid and high temperature or the presence of enzymes to convert into aglycone form. The enzyme used in the enzymatic hydrolysis method is β-glucosidase, and the most suitable conditions for hydrolysis are subject to the highest activity of the enzyme.

nature Hydroxypropyl methacrylate (HPMA) is a commonly used polymer material. 1. Appearance: The appearance of hydroxypropyl methacrylate is a colorless transparent liquid 2. Solubility: Soluble in water and also in most organic solvents, such as alcohols, ethers, esters, and aromatics. 4. Density: The density of hydroxypropyl methacrylate is 1.11-1.18 g/cm3. 6. Chemical stability: It has good chemical stability, is not easy to decompose, and will not react with most chemical substances. 7. Thermal stability: Hydroxypropyl methacrylate has good thermal stability, and its thermal stability is relatively high at high temperatures. 8. Oxidation stability: It has a certain resistance to oxidation and is not prone to oxidation and deterioration. Preparation 1. Add initiators such as hydroxypropyl methacrylate (HPMA) and hydrogen peroxide to the reactor, as well as an appropriate amount of solvents (such as methanol, ethanol, etc.). 2. Seal and shake the reaction kettle or heat it to react, causing the initiator to crack at an appropriate temperature, resulting in free radical polymerization of HPMA. After the reaction is completed, precipitate or precipitate the product with acidic water or organic solvents. 4. Filter and collect the product, wash and dry to obtain the pure product. The above is a simple preparation process for hydroxypropyl methacrylate, and the specific operating parameters and process flow may vary depending on different preparation methods and requirements. application 1. Paint and ink industry: it can be added to paint and ink as lotion and diluent to improve its viscosity, rheology and adhesion. 2. Cosmetics: Can be used in cosmetic products, such as hair gel, curling agents, sunscreen, etc., to thicken, moisturize, and prevent sun damage. 3. Daily necessities: It can be added as a thickener to daily necessities, such as detergents, facial cleansers, toothpaste, etc. 4. Pharmaceutical field: It can be used in drug sustained-release systems, such as artificial joint lubricants or eye drops for injection. In the future, with the continuous development of technology, the application prospects of hydroxypropyl methacrylate will become increasingly broad. For example, in the fields of biomedicine and drug delivery, cell delivery, and the preparation of nanomaterials, polymer materials such as hydroxypropyl methacrylate are also useful

Anhui Sinotech company strictly select GMP products, support customer registration , and provide professional services to chemical customers in the global market.Purchase Xylitol CAS NO.:87-99-0,inquiry Anhui Sinotech . Name: Xylitol CAS No.: 87-99-0 Appearance: White crystal or crystalline powder Molecular formula: C5H12O5 Molecular Weight: 152.15 Melting point: 61~61.5℃ Boiling point: 215~217℃ Solubility: Easily soluble in water, soluble in ethanol and pyridine solvents. Molecular structure: Description: Xylitol CAS NO.:87-99-0 is an organic compound native to Finland. It is a natural sweetener extracted from birch, oak, corn cob, bagasse and other plant materials. In nature, xylitol has a wide distribution range and is widely found in various fruits, vegetables and grains, but the content is very low. The sweetness of xylitol is comparable to that of sucrose. After being dissolved in water, it can absorb a lot of heat. It is the one with the highest endothermic value among all sugar alcohol sweeteners. Therefore, when consumed in solid form, it produces a pleasant cooling sensation in the mouth. Xylitol does not cause dental caries and has the effect of preventing dental caries. Metabolism is not regulated by insulin, it is completely metabolized in the human body, with a calorific value of 10kJ/g, which can be used as a heat source for diabetic patients. Application： Xylitol CAS NO.:87-99-0 can be used to replace sugar in food processing such as candy, cakes, beverages, baked goods, alcohol additives, yogurt, chocolate, chewing gum, jam, jelly, condensed milk, etc. According to normal production needs.
