For professionals in the pharmaceutical and chemical industries, identifying and procuring essential raw materials efficiently is a core responsibility. Methyl 4-amino-5-ethylsulfonyl-2-methoxybenzoate, identified by CAS number 80036-89-1, is a key intermediate in the synthesis of Amisulpride. This guide aims to assist buyers in making informed decisions when seeking to purchase this compound, emphasizing quality, supplier reliability, and cost-effectiveness.

Understanding the Product and Its Requirements

Methyl 4-amino-5-ethylsulfonyl-2-methoxybenzoate (molecular formula C11H15NO5S) is a chemical compound used primarily as an intermediate in the pharmaceutical sector. Buyers typically require this compound to meet stringent specifications, including a purity level of 99% or higher, minimal moisture content, and low levels of heavy metals and other impurities. The physical form is usually a white powder. These specifications are critical for ensuring the successful synthesis of the final Amisulpride API and for meeting regulatory standards. It's important for buyers to review the Certificate of Analysis (COA) provided by suppliers to verify these parameters.

Identifying Reliable Suppliers and Manufacturers

The global market offers numerous sources for Methyl 4-amino-5-ethylsulfonyl-2-methoxybenzoate. However, establishing a robust supply chain involves partnering with credible manufacturers and suppliers. When looking to buy this chemical, consider suppliers who are manufacturers themselves, particularly those located in China, known for their substantial chemical production capabilities. A reputable manufacturer will demonstrate a commitment to quality control, offer competitive pricing, and provide necessary documentation like MSDS and COAs. Online chemical marketplaces and directories can be valuable tools for identifying potential suppliers, but due diligence is essential.

Negotiating Price and Ensuring Supply

Pricing for chemical intermediates can vary significantly based on purity, volume, and supplier. When requesting a quote for Methyl 4-amino-5-ethylsulfonyl-2-methoxybenzoate, be clear about your quantity requirements and desired specifications. Direct manufacturers are often in a better position to offer more competitive pricing, especially for bulk purchases. Building a strong relationship with a chosen supplier can lead to better pricing over time and ensure a more reliable supply chain. Consider suppliers who package the material appropriately (e.g., 25kg drums) and provide guidance on proper storage to maintain product integrity.

In summary, procuring Methyl 4-amino-5-ethylsulfonyl-2-methoxybenzoate requires a strategic approach, focusing on product specifications, supplier credibility, and cost management. By conducting thorough research and engaging with qualified manufacturers, pharmaceutical professionals can secure a consistent and high-quality supply of this crucial Amisulpride intermediate.
