CAS 7440-42-8

Boron

Description:

Boron, with the CAS number 7440-42-8, is a metalloid element that exhibits unique characteristics. It is typically found in nature in the form of borates and is known for its high melting point and hardness. Boron has a relatively low density and is a poor conductor of electricity at room temperature, but it can exhibit semiconducting properties under certain conditions. It exists in several allotropes, with amorphous and crystalline forms being the most common. Chemically, boron is trivalent, meaning it typically forms three bonds with other elements, and it readily reacts with oxygen, nitrogen, and other nonmetals. Boron compounds, such as boric acid and boron carbide, are widely used in various applications, including glass manufacturing, ceramics, and as a semiconductor in electronics. Additionally, boron plays a crucial role in biological systems, particularly in plant growth, although its exact biological function is still being studied. Overall, boron's unique properties make it an important element in both industrial and scientific contexts.

Controlled Product

CAS: 7440-42-8

Boron is a chemical element that has the symbol B and atomic number 5. Boron is a metalloid, which means that it has properties of both metals and nonmetals. It is not very reactive, so it does not combine with other elements to form compounds. Boron occurs in some plants, such as roses or wheat; in the soil; and in seawater. Boron can also be found in many foods, including raisins, almonds, and walnuts. Boron has been used as a nutrient solution for plants to increase their growth rate and improve the quality of their yield. The coordination geometry of boron varies depending on its environment. In biological samples boron can be detected using polymerase chain reaction (PCR) with magnesium salt as a stabilizer. Plasma mass spectrometry can also be used to detect boron. Active antiretroviral therapy has been shown to decrease levels of boron in plasma by 30%. Struct
