Information about Derivative (chemistry)
In chemistry, a derivative is a compound that is formed from a similar compound or a compound that can be imagined to arise from another compound, if one atom is replaced with another atom or group of atoms.[1] The latter definition is common in organic chemistry. In biochemistry, the word is used about compounds that at least theoretically can be formed from the compound.<ref name-Oxford> Oxford Dictionary of Biochemistry and Molecular Biology. Oxford University Press. ISBN 0-19-850673-2.
Chemical derivatives may be used to facilitate analysis. For example, melting point (MP) analysis can assist in identification of many organic compounds. A crystalline derivative may be prepared, such as a semicarbazone or 2,4-dinitrophenylhydrazone (derived from aldehydes/ketones), as a simple way of verifying the identity of the original compound, assuming that a table of derivative MP values is available.[2] Prior to the advent of spectroscopic analysis, such methods were widely used.
