（Ammonium perchlorate），It is an inorganic compound,  CAS number ：7790-98-9,  chemical formula is NH4ClO4, it is a white crystalline powder, deliquescence, soluble in water, slightly soluble in ethanol, acetone, soluble in methanol, insoluble in ether, ethyl acetate Esters, hazard symbol O, are oxidizing agents.

Common uses are as follows:

1. It is used as the raw material for the manufacture of diborane and other high-energy fuels, and is also used in the pharmaceutical industry.

2. It can be used as a compounding agent, oxidant and analytical reagent for ammonium perchlorate explosives.

3. Used in the manufacture of other borohydride salts, reducing agents, wood pulp bleaching, and plastic foaming agents.

4. It can be used as rocket propellant and explosive compounding agent, and can also be used to make fireworks, artificial anti-hail agents, etc.

5. Can be used as engraving agent. In addition, it is used for the determination of phosphorus content in agricultural scientific research.

6. The spacecraft can use a solid mixture of aluminum powder and ammonium perchlorate (NH4ClO4) as fuel. When ignited, the aluminum powder is oxidized and exothermic to cause the decomposition of ammonium perchlorate.

Stability: Explosive when mixed with combustible material. Incompatible with organics, paper, wood shavings, etc. May explode if heated under confinement or as a result of friction. Incompatible with metals, reducing agents, strong acids.

Notice：In ammonium perchlorate(AP) production, chlorate impurity in the raw material will influence the thermostability of AP.

For all we know,Perchlorate (ClO(4)(-)) is the dissociated anion of perchlorate (such as ammonium, potassium and sodium perchlorate) and is a new type of persistent pollutant characterized by fast diffusion, It has high stability and is difficult to degrade, and its environmental pollution has attracted great attention. At present, there are only reports about perchlorate, which mainly focus on interfering with the synthesis and secretion of thyroxine, affecting the normal metabolism of the human body, and thus hindering the normal human body. growth and development.

Therefore, now the relevant researchers have proposed the following experimental methods:

Consists of an untreated control group and five treatment groups that were continuously exposed to AP through drinking water at dose levels of 0.01, 0.05, 0.2, 1.0, and 10.0 mg/kg/day. The study design included a 30-day non-treatment recovery period to assess the reversibility of any AP-induced effects at levels of 0.05, 1.0, and 10.0 mg/kg/day. The study also investigated the potential effects of AP on male sperm parameters, female estrus cycle, bone marrow micronucleus formation and serum hormone levels, namely triiodothyronine (T(3)), thyroxine (T(4)) and Thyroid-stimulating hormone (thyroid-stimulating hormone). No toxicologically significant differences were observed between the control and AP-treated groups in terms of hematology, survival, food consumption, clinical observations, body weight, water consumption, ophthalmology, clinical chemistry, estrus cycle, sperm parameters, or bone marrow micronucleus formation difference. AP produced target organ effects at a level of 10 mg/kg/day in the thyroid of male and female rats after 14 and 90 days of exposure. This effect is characterized by a marked increase in thyroid weight, and thyroid histopathology consists primarily of follicular cell hypertrophy, microfollicular formation, and colloid depletion.
