Key Applications in Pharmaceutical & Agrochemical Synthesis
Our Pyrazole (CAS 288-13-1) serves as a fundamental building block across multiple high-value industries. We understand that for our global clients, the reactivity and stability of the 1,2-Diazole ring are critical for successful downstream synthesis.
Role as a Core Pharmaceutical Intermediate
In the pharmaceutical sector, Pyrazole is indispensable. It acts as a primary Celecoxib intermediate, essential for the production of specific NSAIDs (Non-Steroidal Anti-Inflammatory Drugs). The unique structure allows for the development of potent analgesic and anti-inflammatory medications. We ensure our supply meets the rigorous purity standards required for these sensitive pharmaceutical intermediates.
Agrochemical Building Blocks
Beyond medicine, we supply the agricultural industry with reliable agrochemical building blocks. Pyrazole derivatives are key components in the synthesis of advanced crop protection agents, including:
- Fungicides: To control fungal pathogens in large-scale farming.
- Insecticides: For effective pest management solutions.
- Herbicides: For targeted weed control formulations.
Usage in Dye Synthesis & Energetic Materials
While pharma and agro are our biggest volume movers, we also support niche industrial applications. The compound is utilized in the creation of specialized industrial dyes and, due to its nitrogen-rich composition, plays a role in the research and development of energetic materials.
Why Pyrazole is the Preferred Nitrogen-Containing Heterocycle
Chemists prefer Pyrazole because of its balanced reactivity. As a nitrogen-containing heterocycle, it offers excellent thermal stability and versatility in substitution reactions. This makes it the go-to scaffold for designing complex bioactive molecules compared to other heterocyclic options.
Quality Assurance & Regulatory Compliance
We understand that consistency is the most critical factor when sourcing chemical raw materials. Our quality control system is designed to eliminate variability between batches, ensuring that the Pyrazole (CAS 288-13-1) you receive performs exactly as expected in your synthesis processes.
Rigorous Testing Protocols
To guarantee the integrity of our high-purity Pyrazole, we employ a multi-step analysis process before any product leaves our facility. We don’t just rely on basic checks; we validate chemical identity and purity using advanced instrumentation.
- GC & HPLC Analysis: Used to confirm purity levels (typically ≥ 99.0%) and detect trace organic impurities.
- NMR Spectroscopy: Verifies the molecular structure and ensures the correct isomer profile.
- Moisture Analysis: Strictly monitored to prevent degradation, as Pyrazole can be sensitive to environmental conditions.
Comprehensive Documentation & Transparency
Global manufacturing requires complete traceability. We provide a full suite of technical documents to support your regulatory filings and internal audits:
- Certificate of Analysis (COA): Detailed batch-specific data.
- MSDS/SDS: Updated safety data sheets compliant with international safety standards.
- Route of Synthesis (ROS): Available upon request for clients requiring deep supply chain visibility.
Managing Impurity Profiles & Standards
For clients using 1,2-Diazole as a pharmaceutical intermediate, controlling the impurity profile is non-negotiable. We strictly manage side-reaction byproducts to ensure our material is suitable for sensitive applications. Our operations align with ISO standards and we actively monitor REACH compliance requirements to facilitate smooth export to European and global markets.
