This unit measures the amount of a chemical substance, representing one billionth of a mole (10⁻⁹ mol). It is heavily used in biochemistry, pharmacology, and molecular biology to quantify trace amounts of proteins, DNA, or drug concentrations in small samples. Working at this scale allows researchers to track cellular processes without needing large volumes of reagents.
