Manufacturer Good Price Omega 3 powder CAS:308081-97-2
OMEGA-3, also known as ω-3, Ω-3, w-3, n-3. There are three main types of ω-3 fatty acids. The important essential ω3 fatty acids include α-linolenic acid, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), which are polyunsaturated fatty acids.
Found in Antarctic krill, deep-sea fish and some plants, it is very beneficial to human health. Chemically, OMEGA-3 is a long chain of carbon and hydrogen atoms linked together (more than 18 carbon atoms) with three to six unsaturated bonds (double bonds). It is called OMEGA 3 because its first unsaturated bond is on the third carbon atom of the methyl end.CAS: 308081-97-2

Manufacturer Good Price Aniline CAS:62-53-3
Aniline is the simplest aromatic amine, benzene molecule in a hydrogen atom for the amino group of compounds generated, colorless oil flammable liquid, strong smell. The melting point is -6.3℃, the boiling point is 184℃, the relative density is 1.0217(20/4℃), the refractive index is 1.5863, the flash point (open cup) is 70℃, the spontaneous combustion point is 770℃, the decomposition is heated to 370℃, slightly soluble in water, easily soluble in ethanol, ether, chloroform and other organic solvents. Turns brown Chemicalbook color when exposed to air or sunlight. Available steam distillation, distillation to add a small amount of zinc powder to prevent oxidation. 10 ~ 15ppm NaBH4 can be added to the purified aniline to prevent oxidation deterioration. Aniline solution is basic, and acid is easy to form salt. The hydrogen atom on its amino group can be replaced by a hydrocarbon or acyl group to form secondary or tertiary anilines and acyl anilines. When the substitution reaction is carried out, the adjacent and para-substituted products are mainly formed. Reaction with nitrite yields diazo salts from which a series of benzene derivatives and azo compounds can be made.

Manufacturer Good Price Aluminosilicate Cenosphere CAS:66402-68-4
Physical performance:
Fly ash is a solid waste discharged from coal-fired power plants. Aluminosilicate Cenosphere is hollow beads extracted from fly ash, accounting for about 1% ~ 3% of the total amount of fly ash.
Characteristics:
The mass loss of floating beads in strong acid-base solutions such as 10% hydrochloric acid, sulfuric acid, nitric acid and potassium hydroxide for 24 hours is 1.07% ~ 2.15%, and 11.58% in 1% hydrofluoric acid. Therefore, floating beads have strong corrosion resistance to general strong acids and bases, so they can be used in special projects with high requirements for acid-base resistance (except hydrofluoric acid)..CAS: 66402-68-4

Manufacturer Good Price Potassium Phosphate (Dibasic) CAS:7758-11-4
Dipotassium phosphate (K2HPO4) is a common source of phosphorus and potassium, which is often used as a fertilizer. Dipotassium phosphate is also widely applied in the food industry, such as food additive and electrolyte replenisher for workout supplement. Another usage of dipotassium phosphate is as a medicine, who serves as a diuretic or laxative. Besides, Dipotassium phosphate is employed in the production of imitation dairy creamers to prevent coagulation and used in certain powders to prepare beverages. In addition, Dipotassium phosphate is commonly seen in chemical laboratories for producing buffer solutions and trypticase soy agar which is used to make agar plates for culturing bacteria.
