Description
1,2,3A,4,5,6,7,7A-Octahydro-7-Hydroxy-6-Methylene-2,5-Diphenyl-3H-Pyrazolo[4,3-C]Pyridazin-3-One is a complex, high-purity heterocyclic organic compound with a fused pyrazolo-pyridazinone core structure. This compound serves as a critical advanced intermediate in the synthesis of novel active pharmaceutical ingredients (APIs) and fine chemicals. It is primarily required by pharmaceutical R&D laboratories and specialty chemical manufacturers engaged in developing new therapeutic agents and high-value chemical entities.
Application
- Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in central nervous system (CNS) and anti-inflammatory research.
- Organic Synthesis Research: Serves as a versatile scaffold in medicinal chemistry for structure-activity relationship (SAR) studies and lead optimization.
- Fine Chemical Production: Used in the manufacture of complex, high-value specialty chemicals for agrochemical and material science applications.
- Academic & Contract Research: Essential reagent for universities and CROs (Contract Research Organizations) exploring new heterocyclic chemistry and pharmacological pathways.
- Process Development: Employed in scaling up synthetic routes from laboratory to pilot plant scale for new chemical entities.
