In organic chemistry, the term "reagent" denotes a chemical ingredient (a compound or mixture, typically of small organic or inorganic molecules) introduced to bring about the desired transformation of an organic substance. Examples include Collins's reagent, Fenton's reagent, and Grignard's reagents. In analytical chemistry, a reagent is a compound or mixture that is used to detect the presence or absence of another substance, e.g. Eg by a color change, or to measure the concentration of a substance, eg. ex. by colorimetry. Examples include Fehling's reagent, Millon's reagent, and Tollens's reagent.
In commercial or laboratory preparations, reagent grade designates chemicals that meet purity standards that ensure scientific precision and reliability for chemical analysis, chemical reactions, or physical tests. Reagent purity standards are set by organizations such as ASTM International or the American Chemical Society. For example, reagent quality water must have very low levels of impurities, such as sodium and chloride ions, silica, and bacteria, as well as very high electrical resistivity. Laboratory products that are less pure, but still useful and inexpensive for undemanding work, can be designated as technical, practical, or crude grade to distinguish them from reactive versions.
