If you are looking for optimized HPLC method to analyze Thiourea 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 Separation of Thiourea, Thiouracil, Methylthiouracil, Propylthiouracil on Primesep P Column by SIELC Technologies

Thiourea, Thiouracil (TU), Methylthiouracil (MTU), and Propylthiouracil (PTU) are organic compounds that belong to the class of thioureas, which are characterized by the presence of a thiocarbonyl functional group (C=S).

Each of these compounds has different properties and uses due to the different structures and substitution patterns on the thiourea core. They are all important molecules in both the field of chemistry and medicine.

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.

Methylthiouracil is an organosulfur with the chemical formula C₅H₆N2OS. It is used primarily in antithyroid preparation. It is also used in the treatment of hyperthyroidism. The drug works by inhibiting the synthesis of thyroid hormones, thereby reducing the excessive production of these hormones seen in conditions such as Graves’ disease. While it is not used medically in the United States, it is said to have mechanism of action and side effects similar to propylthiouracil.

Propylthiouracil (PTU) is a medication with the chemical formula C₇H₁₀N₂OS. It is primarily used to treat hyperthyroidism, a condition where the thyroid gland produces too much thyroid hormone. It belongs to a class of drugs called thioureas and specifically to a subgroup known as thioamides.

PTU works by reducing the amount of thyroid hormone produced by the thyroid gland. It inhibits the enzyme thyroid peroxidase, preventing the iodination of tyrosine residues in thyroglobulin and the coupling of these iodotyrosine residues, which are key steps in the synthesis of thyroid hormones.

Additionally, PTU has a unique property among thioamides – it also inhibits the peripheral conversion of thyroxine (T4) to triiodothyronine (T3), the more potent form of thyroid hormone.

The drug is usually taken orally and it’s often used for Graves’ disease, an autoimmune disorder that is the most common cause of hyperthyroidism. However, like all medications, PTU has potential side effects. The most serious one is liver damage, which can be fatal. Because of this, PTU is typically used when other treatments cannot be used, either because of allergies, during early pregnancy, or in preparation for thyroidectomy.

Using a Primesep P Mixed-mode phase column and a mobile phase consisting of water and Acetonitrile (MeCN) with Phosphoric acid as a buffer, Thiourea, Thiouracil, Methylthiouracil, Propylthiouracil can be retained, separated, and analyzed. This analysis method can be UV detected at 200 nm.
