For any chemical or materials manufacturer, the specifications of raw materials directly dictate the quality and performance of the final product. 1,4-Butanediol (BDO), a vital organic chemical intermediate with the CAS number 110-63-4, is no exception. Its physical properties, particularly its purity, are critical for its extensive use in applications ranging from high-performance polymers to fine chemical synthesis. Understanding these specifications is the first step for any procurement manager or R&D scientist when deciding to buy 1,4-butanediol.

The most commonly specified characteristic for industrial-grade 1,4-Butanediol is its appearance: a colorless oily liquid. This visual confirmation is a basic but important indicator of its state. More critically, the assay, or purity level, is paramount. For most demanding applications, such as the production of Polybutylene Terephthalate (PBT) and Tetrahydrofuran (THF), a high purity of ≥99.5% is typically required. This level of purity ensures that the BDO will not introduce unwanted impurities into polymerization reactions or synthetic pathways, which could compromise the mechanical properties of PBT, the solvent efficacy of THF, or the yields in fine chemical processes.

Another key specification is the moisture content, which is usually maintained at ≤0.05%. Water can act as an antagonist in many organic synthesis reactions, particularly those involving sensitive catalysts or demanding anhydrous conditions. Therefore, minimizing moisture content is crucial for process efficiency and product integrity. For manufacturers looking to secure a reliable supply of this essential chemical, partnering with a reputable 1,4-butanediol supplier in China that consistently adheres to these purity standards is indispensable.

The molecular formula for 1,4-Butanediol is C4H10O2, with a molecular weight of 90.121. These fundamental chemical identifiers are important for stoichiometric calculations and reaction design. Its boiling point (228.0±0.0 °C at 760 mmHg) and melting point (around 20 °C) also provide crucial handling and storage information for bulk quantities. When companies inquire about the 1,4-butanediol price, they are often looking for bulk options, such as 200 kg/drum, and need to ensure that the supplier can guarantee these specifications consistently across large batches.

Beyond polymers like PBT and THF, the high purity of 1,4-Butanediol is also critical for its use in producing PTMEG for spandex fibers and, increasingly, for biodegradable plastics like PBAT. In pharmaceutical intermediates and fine chemical synthesis, even trace impurities can lead to significant issues in reaction pathways and final product efficacy. Thus, knowing that your chosen 1,4-butanediol manufacturer prioritizes stringent quality control is non-negotiable.

In conclusion, understanding the specifications of 1,4-Butanediol – from its colorless oily liquid appearance to its high purity (≥99.5%) and low moisture content (≤0.05%) – is fundamental for any manufacturer relying on this versatile chemical.
