A high-performance liquid chromatographic (HPLC) method is described for the quantitativedetermination of some aliphatic aldehydes and beta-hydroxyaldehydes as their 2,4-dinitrophenylhydrazone derivatives. A method is described for the preparation of derivatives for those beta-hydroxyaldehydes where no reference compounds of known purity are available. The detection limit of the method was 4.3-21
