What is Compound?
A compound is a pure substance consisting of two or more different elements chemically bonded together in a fixed ratio by mass. Compounds have properties different from their constituent elements and can only be separated into elements by chemical means. Water (H₂O), sodium chloride (NaCl), and glucose (C₆H₁₂O₆) are examples. Compounds are distinct from mixtures.

A compound is a pure substance consisting of two or more different elements chemically bonded together in a fixed ratio by mass. Compounds have properties different from their constituent elements and can only be separated into elements by chemical means. Water (H₂O), sodium chloride (NaCl), and glucose (C₆H₁₂O₆) are examples. Compounds are distinct from mixtures.
Compounds are the foundation of all chemistry: water (H₂O), table salt (NaCl), glucose (C₆H₁₂O₆), and thousands of industrial and pharmaceutical chemicals are all compounds. The synthesis, analysis, and transformation of compounds is the central activity of chemistry.
Safety depends entirely on the specific compound. Some compounds are inert (NaCl, SiO₂); others are highly toxic (HCN, dioxins), reactive (peroxides, organolithiums), or carcinogenic (benzene, asbestos). Never assume a compound is safe without consulting its SDS.
