For professionals in the pharmaceutical industry, the procurement of chemical intermediates is a critical process that directly impacts product quality, research timelines, and manufacturing efficiency. 2-Aminoethanesulphonamide Monohydrochloride (CAS 89756-60-5) is a prime example of such an essential intermediate. This article serves as a practical buying guide for researchers, formulators, and procurement specialists looking to acquire this high-purity compound.

Understanding the Product: Key Specifications

When considering a purchase, it's vital to be aware of the key characteristics of 2-Aminoethanesulphonamide Monohydrochloride:

• Chemical Identity: Ensure the CAS number (89756-60-5) and molecular formula (C2H8N2O2S·HCl) are correct. Synonyms like Taurinamide HCl or 2-Aminoethanesulfonamide hydrochloride should also be recognized.
• Appearance: It is typically supplied as a White Crystalline Powder. Deviations from this should be carefully scrutinized.
• Purity: For pharmaceutical applications, a high purity is non-negotiable, usually a minimum of 98.5% or 99%. Always request a Certificate of Analysis (CoA) that confirms the purity and details any impurities.
• Physical Properties: Information on melting point (typically around 130-135 °C) and solubility (e.g., slightly soluble in water, methanol, DMSO) can be important for handling and processing.
• Molecular Weight: Approximately 160.62 g/mol.

Applications Driving Demand

The primary demand for this intermediate stems from its role in synthesizing sulfonamide-based pharmaceuticals. This includes antimicrobial agents, diuretics, and other therapeutic compounds. Its specific chemical structure makes it a versatile building block for medicinal chemists aiming to develop new drugs with targeted actions.

The Procurement Process: What to Look For in a Supplier

Selecting the right supplier is as crucial as the product itself. When you decide to buy 2-Aminoethanesulphonamide Monohydrochloride, evaluate potential suppliers based on:

• Manufacturing Capabilities: A supplier that is also a manufacturer can offer better control over quality and pricing. Look for indications of production capacity and certifications (e.g., ISO).
• Quality Assurance Systems: Robust quality control measures, including well-equipped analytical laboratories for testing purity and identity, are essential.
• Supply Chain Reliability: Can the supplier guarantee consistent availability and on-time delivery? Inquire about their production schedules and logistical capabilities, especially for international shipments.
• Pricing and Payment Terms: Obtain detailed quotes and compare them across different suppliers. Understand their payment terms, Incoterms (FOB, CFR, CIF), and minimum order quantities (MOQ).
• Customer Service and Technical Support: Responsive customer service and readily available technical expertise can resolve queries and facilitate a smooth transaction.

Strategies for Efficient Purchasing

• Request Samples: Before committing to large orders, request samples for internal testing and validation.
• Negotiate Volume Discounts: For larger quantities, direct negotiation with manufacturers can yield significant cost savings.
• Long-Term Agreements: For ongoing research or manufacturing needs, consider establishing long-term supply agreements to ensure steady pricing and guaranteed supply.

By approaching the purchase of 2-Aminoethanesulphonamide Monohydrochloride with a thorough understanding of its properties and a strategic supplier evaluation process, pharmaceutical professionals can secure a high-quality intermediate that supports their critical development and production goals.
