The chemical compound ammonium nitrate, the nitrate of ammonia with the chemical formula NH₄NO₃, is a white powder at room temperature and standard pressure. It is commonly used in agriculture as a high-nitrogen fertilizer, and it has also been used as an oxidizing agent in explosives, including improvised explosive devices.

Thymine is one of the four bases in the nucleic acid of DNA that make up the letters ATGC. The others are adenine, guanine, and cytosine. Thymine (T) always pairs with adenine. Thymine is also known as 5-methyluracil, a pyrimidine nucleobase. As the name suggests, thymine may be derived by methylation of uracil at the 5th carbon. In RNA, thymine is replaced with uracil in most cases. In DNA, thymine(T) binds to adenine (A) via two hydrogen bonds to assist in stabilizing the nucleic acid structures.

Uranyl acetate (UO₂(CH₃COO)₂·2H₂O) is a yellow free-flowing crystalline solid of yellow rhombic crystals with a slight acetic odor.

Allyl isothiocyanate is the chemical compound responsible for the pungent taste of mustard, horseradish and wasabi. It is a colorless to pale yellow liquid that is slightly soluble in water, but well soluble in most organic solvents.
