For pharmaceutical manufacturers engaged in the production of Amisulpride, the sourcing of high-quality intermediates is paramount. Methyl 4-amino-5-ethylsulfonyl-2-methoxybenzoate, identified by CAS number 80036-89-1, stands as a crucial building block in this synthesis. Understanding the critical factors when procuring this chemical is essential for ensuring product efficacy, consistency, and cost-effectiveness.

Understanding the Intermediate: Methyl 4-amino-5-ethylsulfonyl-2-methoxybenzoate

This compound, with the molecular formula C11H15NO5S and a molecular weight of approximately 273.31, is typically supplied as a white powder. Its chemical structure and purity directly impact the yield and quality of the final Amisulpride Active Pharmaceutical Ingredient (API). Manufacturers often look for stringent specifications, including high assay values (≥99%), low moisture content (NMT 0.5%), and minimal heavy metal contamination to meet regulatory requirements and ensure optimal performance in synthesis.

Key Considerations for Pharmaceutical Buyers

When seeking to buy Methyl 4-amino-5-ethylsulfonyl-2-methoxybenzoate, several factors should be prioritized. Firstly, identifying a reliable manufacturer or supplier is crucial. A reputable supplier will not only guarantee product quality through Certificates of Analysis (COA) but also offer a stable supply chain to prevent production disruptions. Location, particularly a supplier based in China, can often offer competitive pricing due to manufacturing efficiencies.

Secondly, pricing is a significant consideration for bulk purchases. Direct manufacturers typically offer more competitive prices compared to intermediaries. It is advisable to request quotes from multiple suppliers to benchmark pricing while ensuring that quality and compliance are not compromised. Understanding the various product numbers and synonyms associated with this chemical, such as Amisulpride Impurity 2 or Amisulpride Impurity 5, can also help in a broader search.

Navigating the Supply Landscape

The global market offers numerous options for sourcing this intermediate. However, for consistent quality and reliable supply, partnering with established chemical manufacturers is key. Companies specializing in pharmaceutical intermediates and fine chemicals are well-positioned to meet the exacting demands of the pharmaceutical industry. Engaging with these suppliers, perhaps through an initial sample request or a detailed inquiry about their manufacturing capabilities, is a prudent step.

Ultimately, securing a dependable source for Methyl 4-amino-5-ethylsulfonyl-2-methoxybenzoate involves a careful balance of quality assurance, supply chain reliability, and competitive pricing. By focusing on these aspects, pharmaceutical companies can ensure the smooth and efficient production of Amisulpride.
