Peptides with two or more basic residues, including those with post-translational modifications (PTMs), such as methylation and phosphorylation, can be highly hydrophilic and, therefore, are often difficult to be retained on a reversed-phase (RP) column. In addition, these highly hydrophilic

2-Nitrophenylhydrazine (2-NPH) is widely used for the derivatization of carboxylic acids, aldehydes and ketones, in industrial and biological samples. These compounds react with 2-NPH to form derivatives, which are separated by high-performance liquid chromatography (HPLC) and detected with diode array

Direct derivatization of saponified fats and oils with 2-nitrophenylhydrazine hydrochloride produced corresponding fatty acid hydrazides without time-consuming sample cleanup and/or extraction steps. Hydrazides were injected directly into a liquid chromatograph. Improved isocratic separation was achieved within only 22 min for

A novel high-performance liquid chromatographic method for biologically important fatty acids incorporated into platelet phospholipids in esterified form has been developed. 2-Nitrophenylhydrazine hydrochloride was used as a pre-column labelling agent to convert the saponified platelet phospholipids directly into corresponding fatty
