English name: 2,4-D,2,4-Dichlorophenoxyacetic acid, Amidox, B-Selektonon, U-5043, Crotilin Other names: 2,4-D, 2,4-D acid, 2,4-dichlorobenzene Oxyacetic acid CAS number: 94-75-7 C8H6Cl2O3 = 221.04 grade: CP content: ≥ 98.0% Melting point: 138 ~ 141 ° C Ethanol dissolution test: qualified dry weight loss: ≤ 1.0% trait: white crystal. Soluble in ethanol, ether, and other organic solvents, almost insoluble in water. Relative density (d304) 1.565. The temperature of 138 ° C. The boiling point of 160 ° C (53.33 Pa). Moderately toxic, half lethal dose (rat, oral) 375 mg/kg. Possible use of carcinogenicity: biochemical research. Herbicides, plant growth agents, and organic microanalytical standards for the determination of carbon and hydrogen. 2,4-D is a representative synthetic plant growth hormone (auxin). It has high activity in the conventional plant growth hormone quantification method, but it is quite effective in the oat elongation test using the plant growth hormone standard quantification method. It is purple when treated with chromotropic acid and can be used for colorimetric quantification. This substance is used on a large scale as a herbicide and prevents early fruit exfoliating agents. It can be decomposed by bacteria such as Gram-negative cocci and Flavobacterium aquatile. Save: RT
Vitamins are organic compounds and vital nutrients that an organism requires in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet.
Your body needs them to work properly, so you grow and develop just like you should. They are essential for the normal growth and development of a multicellular organism. Once growth and development are completed, vitamins remain essential nutrients for the healthy maintenance of the cells, tissues, and organs that make up a multicellular organism; they also enable a multicellular life form to efficiently use chemical energy provided by food it eats, and to help process the proteins, carbohydrates, and fats required for respiration.
