Amitraz
Amitraz is also known as acaricide, amitraz and acaricide. It is a kind of broad-spectrum amitraz insecticide, which belongs to moderate toxicity. The original drug is white or yellow needle like crystal with the taste of some carbonamines, with a density of 0.3, melting point of 86-87 ℃, vapor pressure of 506.6 × 10-7pa at 20 ℃, slightly soluble in water, soluble in xylene, acetone, methanol and other organic solvents. It is stable for temperature and light under anhydrous condition. Unstable in acid. It is not inflammable and explosive. It is easy to decompose and deteriorate when stored in a humid place for a long time. It has the functions of contact killing, antifeeding and repellent, as well as stomach poison, fumigation and inhaling. It is effective for all kinds of mites, but not for overwintering eggs. It has a variety of toxic mechanisms, mainly inhibiting the activity of monoamine oxidase and stimulating the non cholinergic synapses in the central nervous system of mites. Mites resistant to other acaricides also had higher activity. The effective period is 40-50 days. It is mainly used in fruit trees, vegetables, tea, cotton, soybeans, beets and other crops to control all kinds of mites. It has good control effect on wood lice, some Lepidoptera eggs, scale, aphid, cotton bollworm, pink bollworm and so on. It can also control tick mites of cattle, sheep and bee mites. Dimeform can be mixed with organophosphorus, pyrethroids, abamectin and other pesticides, which has synergistic effect and can expand the insecticidal spectrum. The mixture was 10.8% avermectin.
Ammonium Acetate
Ammonium acetate is also called "ammonium acetate". Chemical formula nh4c2h3o2. Molecular weight 77.08. White crystal. Melting point 114 ℃, relative density 1.17. Decomposition in high temperature and hot water. Soluble in ethanol, soluble in water, slightly soluble in acetone. Ammonia is easily lost in the air. It is obtained by the interaction of glacial acetic acid and ammonia. In recent years, with the development of pharmaceutical industry, the demand for high purity and low water ammonium acetate has increased dramatically. At present, ammonium acetate has analytical purity, superior purity, pharmaceutical grade and industrial grade, far from meeting the requirements of the pharmaceutical industry. The reason is that the content is low (97% - 98), the pH range is unsatisfactory, the water content is high, the water is easy to be deliquesced, and the storage is difficult. Once the water is absorbed in the storage process, the product can't be treated twice at all. Because it can't be used continuously, it is discarded, resulting in a lot of waste and serious environmental pollution. According to the analysis, the reason why ammonium acetate is easy to absorb moisture is that there is a certain amount of water in the finished product of ammonium acetate. Even the water content of analytical pure, superior grade and reagent grade ammonium acetate is about 2% - 3%. Therefore, ammonium acetate is easy to absorb moisture in the process of storage and use, so it is urgent to study and prepare high purity and low water ammonium acetate.

It is often used to produce hydrogenation, desulfurization and other petroleum refining catalysts, trace element fertilizers, and raw materials for the manufacture of ceramic pigments, pigments and other molybdenum compounds.
Ampicillin
Ampicillin is a beta-lactam antibiotic that has been used extensively to treat bacterial infections since 1961. Until the introduction of ampicillin by the British companyBeecham, penicillin therapies had only been effective against Gram-positive organisms such as staphylococci and streptococci. Ampicillin (originally branded as 'Penbritin') also demonstrated activity against Gram-negative organisms such as H. influenzae, coliforms and Proteus spp. Ampicillin was the first of a number of so-called broad spectrum penicillins subsequently introduced by Beecham. Ampicillin is part of the aminopenicillin family and is roughly equivalent to its successor, amoxicillin in terms of spectrum and level of activity. It can sometimes result in reactions that range in severity from a rash (in the case of patients that may unwittingly have mononucleosis) to potentially lethal allergic reactions such as anaphylaxis.

Aprepitant
Arepidem is used in combination with other antiemetic drugs to prevent acute or delayed nausea and vomiting during the initial or repeated treatment of high or moderate vomiting tumor chemotherapy. It has now been approved in more than 75 countries. The drug blocks the action of substance P by binding with NK-1 receptor (mainly in the central nervous system and its periphery), and it can occupy the NK-1 receptor in the brain through the blood-brain barrier, with high selectivity and affinity, but low affinity for NK-2 and nk-3 receptor. At the same time, the affinity of other drugs (such as dopamine receptor, 5-HT receptor) used to treat chemotherapy-induced nausea and vomiting symptoms is also very low, and the effect of reducing nausea and vomiting is better than other drugs.
