Among the more widely employed derivatization reagents are orthophthalaldehyde (OPA) (1) and Edman’s reagent, phenylisothiocyanate (PITC) (2–5), for which there are numerous publications illustrating their utility. OPA, however, has the significant drawback in that it does not react with secondary amino acids, and some of the derivatives, notably those with Gly and Lys, are unstable. PITC, although reactive with the secondary amino acids, also produces somewhat unstable derivatives, notably with Asp and Glu, which slowly cyclize from the desired phenylthiocarbamyl moieties to their respective phenylthiohydantion derivatives.
