1-Phenylthiourea(CAS: 103-85-5)

1-Phenylthiourea (CAS: 103-85-5) is a white crystalline solid with a molecular weight of approximately 156.23 g/mol. It is practically insoluble in water but soluble in organic solvents like ethanol and acetone. Chemically, it is highly reactive and undergoes hydrolysis and other substitution reactions under basic conditions.

1-Phenylthiourea is typically synthesized by reacting phenyl isothiocyanate with ammonia. The reaction is carried out in an aqueous medium at room temperature, yielding a product with a high yield and good selectivity. Catalysts such as sodium hydroxide are often used to enhance the reaction rate and product purity.

1-Phenylthiourea (CAS: 103-85-5) is primarily used in the pharmaceutical industry as a precursor for the synthesis of various drugs. It is also utilized in the production of dyes and pigments, and as a component in certain polymer formulations. Additionally, it has applications in environmental analysis and as a reagent in analytical chemistry.

When handling 1-Phenylthiourea (CAS: 103-85-5), it is essential to wear appropriate personal protective equipment (PPE) including gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to minimize exposure. Spills should be immediately neutralized with an acid-base indicator and cleaned up using appropriate procedures. Always refer to the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
