1.Usage: N, N-dimethylformamide (DMF) is widely used as drug solvent. N, N-dimethylformamide is a dipole prophilic solvent with physical and chemical properties, so it is suitable for capillary electrophoresis (CE) solvent.
Dimethylformamide appears as a water-white liquid with a faint fishy odor having chemical formula HCON(CH3)2. It is widely used in industries as a solvent, an additive, or an intermediate because of its extensive miscibility with water and most common organic solvents.

1. Used as good solvents on a variety of polymers such as polyethylene, polyvinyl chloride, pan, polyamide, etc. It can be used for acrylic fiber and other synthetic fibers of wet spinning, polyurethane synthesis;
2. Used in the plastic film;
3. Used for catalysts for chemical reactions;
4. Used as a gas absorber for separation and purification of gases in petrochemical industry.
5. Used to remove paint; it can also dissolve some of the low solubility of the pigment, so that the characteristics of dyes with dyes;
6. Used in pesticide industry. It can be used for synthesis of iodine amine pyrimidine, doxycycline, cortisone, vitamin B6,antitumor ammonia acid, furosemide fluorouracil, bile dimension he, etc.
Dimethylformamide (DMF) is a clear, colorless, hygroscopic liquid with a slight amine odor. The solvent properties of DMF are particularly attractive because of the high dielectric constant, the aprotic nature of the solvent, its wide liquid range and low volatility. It is frequently used for chemical reactions and other applications, which require a high solvency power. The product is known as a universal solvent. The high solubility of polyacrylonitrile in DMF, together with the good miscibility of DMF in water makes DMF the preferred solvent to produce acrylic fibers. Also, the spinning of polyurethane based elastomers is performed from DMF based solutions. Another significant application is the use of DMF as a solvent for polyurethane-based coatings on leather and artificial leather fabrics.
Application: It is used in the chemical industry as a solvent, an intermediate, and an additive; for example, in the production of pharmaceuticals, synthetic fibers, resins, agrochemicals, petrochemical industry etc.

Sugar Esters E473, CAS No.37318-31-3 , commonly known as Sucrose esters of fatty acids, manufacturing process by esterifying sucrose with fatty acids. By varying the degree of esterification of the sucrose molecule it is possible to obtain emulsifiers with HLB values ranging from 1 up to 16. It is a light yellow powder, a non-ionic surfactant and is used as an emulsifier in dairy products, baked goods, soft drinks, jelly, cake and candy. Sucrose Fatty Acid Esters are a mixture of mono-, di-, and tri-esters of sucrose with fatty acids derived from edible vegetable or hydrogenated vegetable oils and fats.
As an experienced Sugar Esters manufacturer and supplier, we has been supplying and exporting Sugar Esters for almost 10 years, please be assured to buy from us. Any inquiries about price and the market trend please feel free to contact us, we will reply you within 1 working day.
