UV-Vis Spectrum of Chlorocholine.

If you are looking for optimized HPLC method to analyze Chlorocholine check our HPLC Applications library

For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.

HPLC Method for Mepiquat, Paraquat, Diquat, Chlorocholine on Obelisc R by SIELC Technologies

HPLC Method for Simultaneous Determination of -Quat Herbicides on Obelisc R Column by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Mepiquat, Paraquat, Diquat, Chlorocholine.

Chlormequat is a plant growth regulator with the chemical formula C5H13ClN. It works through inhibiting gibberellin biosynthesis, which leads to reduced cell elongation and thicker stalks.

Mepiquat is a plant growth regulator with the chemical formula C7H16N+.  It is used primarily to control the growth rate and quality of the yield. 

Paraquat is a widely used, non-selective herbicide known for its high efficacy in controlling a wide range of weeds. It has been an important tool in agriculture since its introduction in the mid-20th century. However, its use is accompanied by significant safety concerns due to its high toxicity.

Diquat is an organic dication that is used as a contact herbicide. It has the chemical formula C12H12Br2N2. It is considered moderately toxic and harmful if swallowed, inhaled, or absorbed through skin. It degrades slowly when in nature due to bonding strongly to minerals and organic particles. Due to that, it is no longer approved for use in the European Union.

Mepiquat, Paraquat, Diquat, Chlorocholine can be retained and analyzed using the Obelisc R stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with an ammonium formate buffer. Detection is performed using UV.
