HPLC Method for Analysis of Resorcinol, N,N-Bis (2-hydroxy)-p-phenylenediamine, p-Phenylenediamine and 1-Naphthol on Primesep 100 by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Resorcinol, N,N-Bis(2-hydroxy)-p-phenylenediamine, p-Phenylenediamine and 1-Naphthol
Resorcinol – a chemical compound with the formula C6H4(OH)2. It is a dihydroxybenzene used in various applications, including the production of resins and as a topical antiseptic.
N,N-Bis(2-hydroxyethyl)p-phenylenediamine – a compound used in the manufacture of hair dyes and related products.
p-Phenylenediamine – commonly known as PPD, it’s used in hair dyes and black rubber products.
1-Naphthol – a crystalline compound with the formula C10H7OH. It’s used in the synthesis of dyes and perfumes.
All compounds can be retained, separated, and analyzed using a Primesep 100 mixed-mode stationary phase column. The analysis employs an isocratic method with a simple mobile phase comprising water, acetonitrile (MeCN), and sulfuric acid as a buffer. This method allows for detection using UV at 210 nm
