Description

Pyrazolo[1,5-A]Pyrimidine-3-Acetamide, N,n-Diethyl-5,7-Dimethyl-2-[4-[2-[[(4-Methylphenyl)Sulfonyl]Oxy]Ethoxy]Phenyl]- is a high-purity, advanced pharmaceutical intermediate with a complex heterocyclic structure. This compound matters for its critical role in the synthesis of targeted therapeutic agents, particularly in oncology and antiviral research. It is primarily needed by pharmaceutical R&D laboratories, fine chemical manufacturers, and contract development and manufacturing organizations (CDMOs) engaged in the development of novel active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel drug candidates targeting specific biological pathways.
• Oncology Research: Used in the development of kinase inhibitors and other targeted cancer therapies due to its pyrazolopyrimidine core.
• Antiviral Drug Development: Serves as a precursor in the research and production of compounds with potential antiviral activity.
• Chemical Biology: Employed as a probe or tool compound for studying enzyme function and cellular signaling mechanisms.
• Fine Chemical Synthesis: Utilized in multi-step organic synthesis for creating complex, high-value specialty chemicals.
• Contract Manufacturing: Supplied to CDMOs for scale-up and cGMP production of clinical trial materials and commercial APIs.

Quality Control

Our Pyrazolo[1,5-A]Pyrimidine-3-Acetamide intermediate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for pharmaceutical research. Certificates of Analysis (COA) with full traceability are provided with every shipment, supporting compliance with cGMP and ICH guidelines where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
