For procurement managers and R&D scientists in the chemical and pharmaceutical industries, securing a reliable supply of specialized intermediates like 2-[N,N-BIS(TRIFLUOROMETHANESULFONYL)AMINO]-5-CHLOROPYRIDINE (CAS 145100-51-2) is paramount. This compound, often referred to by its CAS number or as a key triflimide reagent, plays a critical role in synthesizing vinyl trifluoromethanesulfonate and other complex molecules. This guide will help you understand the critical factors when looking to buy this chemical intermediate.

Understanding the Product: CAS 145100-51-2

At its core, 2-[N,N-BIS(TRIFLUOROMETHANESULFONYL)AMINO]-5-CHLOROPYRIDINE is a fine chemical intermediate. Its primary known application is its utility in reacting with ketoenols or dienols to produce high-yield vinyl trifluoromethanesulfonate. This specific reaction pathway makes it a valuable precursor in organic synthesis, particularly for those developing new pharmaceuticals, agrochemicals, or advanced materials. When searching for this product, using the CAS number 145100-51-2 is often the most precise method for identifying the correct chemical entity.

Key Considerations When Purchasing

When engaging with a manufacturer or supplier of Bistrifluoromethylsulfonylaminochloropyridine, several factors deserve your attention:

• Purity: The typical purity specified is 98%. For sensitive synthesis applications, ensuring this level of purity is maintained consistently is crucial. Any deviation can impact reaction yields and product quality.
• Appearance: The product is generally described as a white to off-white powder. Visual inspection and conformity to this description are basic quality checks.
• Pricing and Quantity: For bulk inquiries, understanding the price per kilogram or ton is essential. Discussing minimum order quantities (MOQs) and potential discounts for larger volumes is a standard procurement practice. If you are looking to purchase this chemical, inquire about the most competitive pricing available.
• Supply Chain Stability: Given the specialized nature of such intermediates, a stable supply chain is critical. Partnering with a reputable supplier in China can offer significant advantages in terms of production capacity and global reach.
• Technical Support: A knowledgeable supplier can provide technical data, safety information, and application insights, aiding your R&D and production teams.

Finding a Reliable Supplier

Identifying a trustworthy chemical supplier involves due diligence. Look for companies that:

• Clearly state their product specifications (purity, appearance, CAS number).
• Offer transparent pricing and flexible payment terms (L/C, T/T, etc.).
• Have a clear understanding of logistics, including shipping options (Ocean, Air, DHL, TNT) and Incoterms (FOB, CFR, CIF).
• Possess relevant certifications (e.g., ISO) demonstrating their commitment to quality management.
• Provide responsive customer service to address inquiries and facilitate the purchasing process.

For those seeking to buy Bistrifluoromethylsulfonylaminochloropyridine or inquire about its price, engaging with experienced manufacturers and suppliers is the first step towards securing a consistent and high-quality supply. Understanding the product's applications and the supplier's capabilities will ensure a successful procurement process.
