This article aims to provide R&D professionals with essential information about this intermediate, its significance, and guidance on sourcing it effectively from leading manufacturers.

The Critical Link: 3-Ethynylimidazo[1,2-b]pyridazine in Drug Discovery

The primary significance of 3-Ethynylimidazo[1,2-b]pyridazine lies in its function as a key precursor for Ponatinib. Ponatinib's success in treating challenging cases of CML and Ph+ ALL underscores the importance of its constituent parts. The structural features of 3-ethynylimidazo[1,2-b]pyridazine, specifically the imidazo[1,2-b]pyridazine ring system and the ethynyl group, are essential for creating the molecule's specific kinase inhibition profile. R&D scientists often utilize such intermediates to:

• Explore structure-activity relationships (SAR) for new drug candidates.
• Optimize synthetic routes for novel APIs.
• Conduct preclinical research and early-stage drug development.

Technical Specifications Demanded by R&D

When scientists plan to buy 3-ethynylimidazo[1,2-b]pyridazine for their research, they require precise specifications. The typical appearance is a yellow powder. Crucially, the assay purity should be high, usually stated as ≥96.0% or even ≥98.0% (HPLC). The CAS number 943320-61-4 is the standard identifier. Understanding its molecular formula (C8H5N3) and molecular weight (143.15) aids in experimental design and calculations. Access to safety data sheets (SDS) and spectral data (like NMR or MS) can further validate the intermediate's quality and suitability for sensitive research applications.

Sourcing Strategies: Partnering with Chinese Manufacturers

The global market offers numerous avenues to acquire 3-ethynylimidazo[1,2-b]pyridazine. However, for cost-effectiveness and reliable supply, many R&D departments turn to Chinese manufacturers. Identifying the right 3-ethynylimidazo[1,2-b]pyridazine supplier in China involves looking for companies that specialize in fine chemicals and pharmaceutical intermediates. These suppliers often provide detailed product documentation and can handle inquiries for research-scale quantities efficiently.

Key considerations when sourcing:

• Purity Levels: Confirm the assay method (e.g., HPLC, GC) and ensure it meets your research needs.
• Small Batch Availability: Many research projects require gram quantities, so check if suppliers offer these sizes.
• Lead Times: Factor in shipping and handling when planning your experiments.
• Supplier Reputation: Seek reviews or testimonials from other researchers if possible.

Initiating a Purchase for Research Purposes

To purchase 3-ethynylimidazo[1,2-b]pyridazine for your lab, begin by contacting potential suppliers with a clear request. Detail the quantity needed (e.g., 5g, 10g), desired purity, and your intended use (e.g., R&D). You can then compare the quotations received from various Ponatinib intermediate manufacturers. Discussing the pharmaceutical intermediate price for research quantities is standard practice.

In conclusion, 3-Ethynylimidazo[1,2-b]pyridazine is a critical component for modern pharmaceutical R&D, especially in the oncology space. By understanding its technical specifications and employing smart sourcing strategies, researchers can efficiently obtain this vital intermediate from trusted Chinese manufacturers, accelerating their path to discovery.
