CAS 621-00-1

N,N′-Bis(4-methylphenyl)urea

Description:

N,N′-Bis(4-methylphenyl)urea, with the CAS number 621-00-1, is an organic compound characterized by its urea functional group and two 4-methylphenyl substituents. This compound typically appears as a white to off-white crystalline solid. It is known for its relatively high melting point and moderate solubility in organic solvents, such as ethanol and acetone, while being less soluble in water. The presence of the methyl groups on the phenyl rings enhances its lipophilicity, which can influence its biological activity and interactions. N,N′-Bis(4-methylphenyl)urea is often utilized in research and industrial applications, particularly in the synthesis of various organic compounds and as a potential intermediate in the production of pharmaceuticals. Additionally, it may exhibit interesting properties such as fluorescence or photostability, making it relevant in materials science. Safety data should be consulted, as with any chemical, to understand its handling, storage, and potential hazards.

4,4'-Ditolylurea

CAS: 621-00-1

4,4'-Ditolylurea is a synthetic reagent used in the preparation of aldosterone. It is an anhydride that reacts with sulfonic acid to form a ditolylurea. This compound has a specific activity of 10,000 Ci/mmol and can be used in the determination of anhydride-sulfonic acid equilibria. 4,4'-Ditolylurea is usually used as the reagent in a technique called "3-step reaction" to synthesize aldosterone from cholesterol.
