Abstract
Trace analysis of carbonyl compounds in organic samples, using 2,4-dinitrophenylhydrazone method, requires the use of the same carbonyl compounds as calibration standard. We established that methoxyacetone can be used as calibrating substance for oxualkylated products. Moreover, we set the main parameters such as reaction time and colour development time before spectrophotometer reading
