3-Methyl-1-phenyl-2-pyrazolin-5-one belongs to the pyrazolone class of compounds, characterized by a five-membered heterocyclic ring containing two nitrogen atoms. The presence of both methyl and phenyl groups imparts unique electronic properties that enhance its reactivity and solubility in organic solvents. The molecular formula C10H10N2O indicates that this compound contains two nitrogen atoms along with a keto group, contributing to its characteristic reactivity.


The runaway outbreak  has sparked global concern.  As the world’s largest API exporters, the supply pattern of China and India has been affected.  At the same time, with the emergence of a new round of global trade protectionism and increased demand for the security of the pharmaceutical industry chain due to the epidemic, China’s API industry faces new challenges and must accelerate the transformation and upgrading from a big country to a strong one.  To this end, “Pharmaceutical Economic News” specially launched the special planning of “API road to Strong Country”.

In addition to coagulants, flocculants are used to enhance the settling of these aggregates. Polymers, typically synthetic compounds, serve this purpose effectively by binding particles together, resulting in larger, heavier flocs that settle out of the water column more readily. This step not only aids in solids removal but also reduces the volume of sludge that must be processed further.

The ongoing research surrounding CAS 204584-46-7 is focused on expanding its applications. Scientists are investigating its effectiveness in other conditions, such as atopic dermatitis and alopecia areata. Clinical trials aim to determine the long-term effects of Tofacitinib and to find optimal dosing strategies that minimize side effects while maximizing therapeutic benefits.


Ammonium thiocyanate, a versatile chemical compound with the formula NH4SCN, is widely used in various industries due to its unique properties. This colorless crystalline substance is primarily utilized in agriculture, laboratory applications, and chemical synthesis. As the demand for ammonium thiocyanate continues to grow, the role of reliable suppliers is critical in ensuring that industries can access this important compound consistently and safely.
