Trimagnesium dicitrate
Product name:Trimagnesium dicitrate
CAS: 3344-18-1
Molecular Formula: C12H10Mg3O14
Molecular Weight: 451.11
Product description:Magnesium citrate is also called magnesium citrate, white or yellowish powder, non-toxic, non-corrosive, and is formed by magnesium carbonate and citric acid. The magnesium content as high as eleven percent, and contains magnesium are easily absorbed by the body, so is an important source of magnesium supplementation.As normal saline laxative. Before doing any operation, will provide the patient with citric acid magnesium, so Yu Qingkong intestines. This is because it have a tendency to absorb organization moisture, injection after intestinal can draw water out side by side a lot of in vitro. In fact, it still can treat constipation and colon cancer, or diseases associated with colorectal cancer. In addition, the effect of magnesium citrate and prevent kidney stones.

Diflubenzuron
Product name:Diflubenzuron
CAS: 35367-38-5
Molecular Formula: C14H9ClF2N2O2
Molecular Weight: 310.68
Product description:Its insecticidal mechanism and conventional pesticides is very different in the past, neither nerve agents, nor a cholinesterase inhibitor, its role is largely inhibit insect cuticular chitin synthesis, as well as the fat body, pharynx side body such as endocrine and glands and damage effect, thereby preventing insects molting of abnormal condition. Deinsectization urea for benzoic acid phenyl urea class in addition to pesticides, and show urea no. 3 for pest control agent, insecticidal mechanism is also inhibit the synthesis of insect chitin synthase, thus inhibiting the larvae and eggs, pupa of cuticular chitin synthesis, that insects could not normal this insect body deformity and death. Pests after feeding cumulative poisoning, due to lack of chitin, the larvae cannot form new skin, this difficult, pupation blocked; Adult eclosion, spawning; Eggs can not develop normally, lack of hatched larvae cuticle hardness and death, which affects pests whole generation, this is the advantage of deinsectization urea.
