Two other reagents used in HPLC are 9-fluorenyl methoxycarbonyl chloride (FMOC) and phenylisothiocyanate (PITC). 9-fluorenyl methoxycarbonyl chloride is becoming increasingly popular in protein chemistry research because it reacts with secondary amines and also offers rapid analysis of protein hydrolysates. [Pg.50]

PITC has been used extensively in the sequencing of peptides and proteins and reactions under alkaline conditions with both primary and secondary amino acids. The methods of sample preparation and derivatization follow a stringent procedure which involves many labour-intensive stages. However, the resulting phenylthio-carbamyl-amino acids (PTC-AA s) are very stable, and the timing of the derivatization step is not as critical as when using OPA. [Pg.53]

Reaction with phenylisothiocyanate (PITC) in alkaline conditions produces stable phenylthiocarbamyl (PTC) adducts which can be detected either in the ultraviolet below 250 nm or electrochemically. However, this method involves a complex derivatization procedure and offers poorer sensitivity than the alternatives available for individual amino acids. It is useful, however, in conjunction with the automated analysis of peptides when single derivatized residues can be cleaved and analysed after conversion in acidic conditions to phenylthiohydantoins. [Pg.373]
