Uv-Vis Spectrum of Dimethylthiourea
January 22, 2026
If you are looking for optimized HPLC method to analyze Dimethylthiourea 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 Analysis of Dimethylthiourea on Primesep P by SIELC Technologies

Dimethylthiourea is an organic compound containing two methyl groups attached to a thiourea molecule. The chemical formula is (CH3)2NCSNH2. Like other thiourea derivatives, dimethylthiourea has a range of uses in various fields, including research and industrial applications.
In research, it’s often used due to its properties as a good hydrogen bond donor and acceptor, allowing it to participate in a variety of reactions. For example, it can be used as a reducing agent in some types of reactions. It also has some interesting properties in terms of its electrical conductivity and its ability to absorb certain types of radiation, which make it useful in some niche applications.
Using a Primesep P Mixed-mode phase column and a mobile phase consisting of water and Acetonitrile (MeCN) with no buffer, dimethylthiourea can be retained and analyzed. This analysis method can be UV detected at 200 nm.
LOD was determined for this combination of instrument, method, and analyte, and it can vary from one laboratory to another even when the same general type of analysis is being performed.

Thiourea is a versatile chemical compound with the formula (NH2)2CS. It is structurally similar to urea, except that the oxygen atom is replaced by a sulfur atom. It is a white crystalline solid when pure.
Thiourea is used in a variety of applications. It is a reagent in organic synthesis, often used in the toning of silver-gelatin photography prints, as a component of hair preparations and bleaches, and as a radioprotective agent in cancer therapy.
In agriculture, thiourea is used as a soil treatment agent to promote germination and stimulate flowering and fruiting.
Using a Primesep P Mixed-mode phase column and a mobile phase consisting of water and Acetonitrile (MeCN) with no buffer, Thiourea and Dimethylthiourea can be retained, separated, and analyzed. This analysis method can be UV detected at 200 nm.
