In the past, derivative also meant a compound that can be imagined to arise from another compound, if one atom or group of atoms is replaced with another atom or group of atoms,[1] but modern chemical language now uses the term structural analog for this meaning, thus eliminating ambiguity.[citation needed] The term "structural analogue" is common in organic chemistry.
In biochemistry, the word is used for compounds that at least theoretically can be formed from the precursor compound.[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 or ketones), as a simple way of verifying the identity of the original compound, assuming that a table of derivative MP values is available.[3] Prior to the advent of spectroscopic analysis, such methods were widely used.
