For procurement professionals and researchers in the chemical and pharmaceutical industries, the quality of raw materials directly impacts the success of their projects. 1,2-Butanediol (CAS 26171-83-5), a vital intermediate and solvent, requires careful consideration when purchasing to ensure it meets stringent application requirements. This guide outlines key aspects to focus on when buying this compound.

Understanding the Specifications of 1,2-Butanediol

When you intend to buy 1,2-Butanediol, the most critical specification is its purity. Typically, a minimum purity of 99% is sought after for most industrial and research applications. The molecular formula C4H10O2 accurately describes its composition, and the CAS number 26171-83-5 serves as its unique identifier. Beyond purity, other specifications such as water content (often specified as a maximum percentage) and appearance (clear, colorless liquid) are important indicators of quality. Packaging, commonly in 200kg drums, should also be confirmed to match your handling and storage capabilities.

Key Quality Indicators to Verify

• Certificate of Analysis (CoA): Always request a CoA with each batch. This document provides detailed analytical results for key parameters, confirming the product meets the stated specifications.
• Safety Data Sheet (SDS): A comprehensive SDS is essential for safe handling, storage, and transportation. It outlines potential hazards, protective measures, and emergency procedures.
• Manufacturer Reputation: Partnering with established manufacturers, especially those with a proven track record in producing high-purity chemicals, is crucial. Suppliers in China are known for their robust manufacturing capabilities.
• Batch Consistency: For ongoing projects, ensuring consistency between different production batches is vital. Reputable suppliers maintain rigorous quality control processes to guarantee this.

Working with Manufacturers and Suppliers

When you are ready to procure 1,2-Butanediol, engaging directly with manufacturers or their authorized distributors is the most effective approach. Clearly state your requirements, including the CAS number, purity, quantity, and any specific packaging needs. Requesting a quote early in the process allows for budget planning and comparison of offers. Many manufacturers also offer samples, which can be invaluable for in-house testing and validation before placing a large order.

By prioritizing these quality assurance measures, you can confidently source 1,2-Butanediol that aligns with your specific needs, ensuring the success and integrity of your chemical processes. Choosing a reliable supplier, whether domestically or internationally from China, is a cornerstone of effective chemical procurement.
