Bromine is a chemical element with the symbol Br and atomic number 35. It is a halogen that belongs to the same group as chlorine, fluorine, iodine and astatine. Bromine is a reddish-brown liquid at room temperature that evaporates easily and has a strong, unpleasant odor.

Bromine has many uses in various industries, such as medicine, agriculture, photography, flame retardants, water treatment and cosmetics. It is also used to make some organic compounds, such as brominated vegetable oil, which is added to some citrus-flavored soft drinks.

If you are looking for a reliable source of bromine, you have several options depending on your needs and preferences. Here are some of the most common ways to buy bromine:

• Online retailers: You can find many online stores that sell bromine in different forms and quantities. Some examples are Amazon, eBay, Alibaba and ChemWorld. You can compare prices, reviews and shipping options before placing your order. However, you should be careful about the quality and safety of the product, as well as the regulations and restrictions of your country regarding the import and export of bromine.
• Local suppliers: You can also buy bromine from local chemical suppliers or distributors in your area. You can search online or use directories such as Yellow Pages or Yelp to find them. You can visit their physical stores or contact them by phone or email to inquire about their products and services. Buying from local suppliers may offer you more convenience, trust and support than buying from online retailers.

Bromine is one of the few elements that is a liquid at room temperature. It has a brownish-red color with a bleach-like odor, and it dissolves in water. Bromine is a halogen, which means it belongs to the same group as fluorine, chlorine, iodine and astatine. Bromine has seven electrons in its outermost shell, and it can form bonds with other elements by gaining or losing electrons.

Bromine has many interesting facts and properties that make it a unique and important element. Here are some of them:

• Bromine is essential for animals: Although bromine is toxic as a pure element and in high doses, it is an essential element for animals. The bromide ion is a cofactor in collagen synthesis, which is important for connective tissues and wound healing. Bromine is also involved in the production of thyroid hormones, which regulate metabolism and growth.
• Bromine was used as a poison gas: In World War I, xylyl bromide and related bromine compounds were used as poison gas by the German army. These gases caused irritation and inflammation of the eyes, nose, throat and lungs, and could lead to death by suffocation or pulmonary edema . Bromine gas is still considered a chemical weapon today, and its use is prohibited by international law.
• Bromine is found in sea water: Bromine is the tenth most abundant element in sea water with an abundance of 67.3 mg/L. Bromine is also found in some salt lakes, such as the Dead Sea, where it can reach concentrations of up to 5 grams per litre. Bromine is extracted from sea water or salt lakes by passing chlorine gas through them, which displaces bromine as a volatile liquid.
