Description

Pyrazolo[1,5-A]Pyrimidin-7-Ol, 2-(3,4-Dimethoxyphenyl)-5-Phenyl- (9Ci) is a high-value, multi-substituted heterocyclic compound that serves as a critical advanced intermediate in modern synthetic chemistry. Its complex pyrazolopyrimidine core, functionalized with dimethoxyphenyl and phenyl groups, makes it an essential building block for the development of novel active pharmaceutical ingredients (APIs) and functional materials. This compound is primarily sought by research institutions and industrial R&D departments focused on medicinal chemistry, agrochemical discovery, and materials science.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates targeting various therapeutic areas, including kinase inhibitors and anti-inflammatory agents.
• Agrochemical Research: Used as a core scaffold for developing new-generation herbicides, fungicides, and plant growth regulators.
• Organic Light-Emitting Diodes (OLEDs): Serves as a potential electron-transport or host material in the development of advanced optoelectronic devices due to its rigid, conjugated structure.
• Academic & Contract Research: Employed in university and CRO laboratories for method development, structure-activity relationship (SAR) studies, and exploring new chemical spaces.
• Material Science: Investigated as a monomer or additive for creating specialty polymers with unique thermal or electronic properties.
