Description

HPLC Method for Analysis of Crystal Violet , Crystal Violet Lactone , Pararosaniline Hydrochloride on Primesep 100 Column by SIELC Technologies

Pararosaniline ( Basic Red 9 ) is a popular basic magenta dye and part of the triarylmethane family of dyes with the chemical formula C 19 H 17 N 3 . It is a free base version of pararosaniline hydrochloride. Primarily, it is used to dye synthetic materials, to detect sulfur dioxide, and as an antischistosomal.

Crystal Violet ( Methyl Violet 10B ), another basic triarylmethane dye, has the C 25 H 30 ClN 3 . It is frequently used for histological stains and for identifying Gram-positive bacteria. It is said to have antibacterial, antifungal, and anthelmintic properties. It is a common component of navy blue and black inks in printing, inkjet printers, and ball-point pens.

Crystal Violet Lactone , a derivative of Crystal Violet , is a basic thermochromic dye with the chemical formula C 26 H 29 N 3 O 2 . It is widely used as a security marker for various types of fuels as well as carbonless copy papers. It is a slightly yellow crystalline powder that is soluble in nonpolar organic solvents.

These three basic dyes can be separated, retained, and analyzed on a Primesep 100 mixed-mode stationary phase column using an isocratic analytical method with a simple mobile phase of water, Acetonitrile (MeCN), and a sulfuric acid (H2SO4) buffer. This analysis method can be detected in the UV-Vis regime at 540, 590, and 200 nm.
