For procurement managers and research scientists in the pharmaceutical and chemical industries, sourcing specialized compounds like (3R,4S)-Tofacitinib (CAS 1092578-46-5) requires a strategic approach. This chemical intermediate is vital for various research applications, and ensuring a reliable and cost-effective supply is key to project success. This guide aims to provide clarity on how to effectively buy (3R,4S)-Tofacitinib, focusing on quality, supplier selection, and optimal procurement practices.

Understanding the Product: (3R,4S)-Tofacitinib

(3R,4S)-Tofacitinib, with its distinct CAS number 1092578-46-5, molecular formula C16H20N6O, and molecular weight of 312.37, is a stereoisomer of significant interest in pharmaceutical research. Its precise chemical structure and stereochemistry are crucial for its intended applications, often serving as a building block or an impurity standard in drug development. When searching for a (3R,4S)-Tofacitinib supplier, it's imperative to confirm these specifications.

Key Factors When Buying (3R,4S)-Tofacitinib

1. Purity and Quality Assurance: The foremost consideration when purchasing any pharmaceutical intermediate is its purity. Aim for suppliers that provide detailed analytical data, such as High-Performance Liquid Chromatography (HPLC) or Nuclear Magnetic Resonance (NMR) reports, to verify purity levels (typically 98% or higher for this compound). Reputable manufacturers will offer Certificates of Analysis (CoA) to attest to the quality of their product. This ensures that your research or manufacturing process is not compromised by substandard materials.

2. Supplier Reliability and Origin: Identifying a trustworthy (3R,4S)-Tofacitinib manufacturer or supplier is paramount. While many global suppliers exist, many high-quality, cost-effective options are found in China. When looking to purchase this compound, understanding the supplier's track record, production capacity, and commitment to quality control is essential. A well-established Chinese manufacturer can offer both competitive (3R,4S)-Tofacitinib price points and a stable supply chain.

3. Pricing and Bulk Orders: The (3R,4S)-Tofacitinib price can vary significantly based on quantity, purity, and supplier. For organizations requiring larger volumes for R&D or production, negotiating bulk pricing is a standard practice. Inquiring about tiered pricing structures or volume discounts can lead to significant cost savings. Always seek multiple quotes from different suppliers to compare pricing and terms before making a decision.

4. Logistics and Documentation: Understanding shipping conditions, lead times, and required documentation is vital. As a chemical supplier, we ensure efficient logistics, whether you are looking to buy (3R,4S)-Tofacitinib for domestic use or international import. Compliance with international shipping regulations and the provision of necessary safety data sheets (SDS) are part of our commitment.

5. Technical Support and Customization: Beyond just supplying the chemical, consider suppliers who offer technical support. This can be invaluable for troubleshooting, understanding application nuances, or even discussing custom synthesis needs. For example, if specific packaging or analytical data requirements exist, a responsive supplier can often accommodate these requests.
