The world of organic chemistry is built upon a foundation of versatile building blocks and reactive intermediates that enable the construction of complex molecules. Methane Sulfonic Acid N-Hydroxysuccinimide Ester, identified by CAS number 54769-40-3, stands as a prime example of such a crucial chemical intermediate. Characterized by its appearance as a white to off-white solid powder and a high purity of typically 98.0% (HPLC), this compound is a valuable asset for a wide range of synthetic applications, particularly in the pharmaceutical and specialty chemical sectors.

Its primary utility stems from its function as an activating agent. The N-hydroxysuccinimide moiety, when esterified with methane sulfonic acid, creates a highly reactive ester that readily undergoes nucleophilic substitution. This property makes it an excellent choice for facilitating reactions that require the formation of new carbon-nitrogen or carbon-oxygen bonds. While its most recognized role is in peptide synthesis, its applications extend far beyond this specific area of organic chemistry.

As a chemical intermediate, this compound can be employed in various conjugation chemistries. For instance, it can be used to functionalize biomolecules, attach labels, or prepare advanced materials. Researchers looking to buy such intermediates often seek manufacturers who can guarantee consistent quality and scale-up capabilities. The demand for high-purity reagents is universal across research and industrial applications, ensuring that the final products meet stringent performance criteria.

The sourcing of such intermediates is a significant consideration for many businesses. Partnering with reliable suppliers and manufacturers, especially those operating in major chemical production regions like China, can offer significant advantages in terms of cost and accessibility. When considering a purchase, it is prudent to seek out suppliers who provide detailed product specifications, including purity, physical properties, and safety data. This due diligence ensures that the selected intermediate will perform as expected in the intended application.

Furthermore, the price of Methane Sulfonic Acid N-Hydroxysuccinimide Ester is a factor for many procurement departments. Bulk purchasing from manufacturers can often lead to substantial cost reductions. Therefore, companies that require this intermediate for ongoing production or extensive research projects should actively engage with suppliers to obtain competitive quotes. Understanding the market landscape, identifying key manufacturers, and fostering strong supplier relationships are all essential components of an effective chemical procurement strategy. In essence, Methane Sulfonic Acid N-Hydroxysuccinimide Ester is more than just a reagent; it is a key enabler for innovation across multiple chemical disciplines.
