For any chemical procurement, a clear understanding of product specifications is fundamental to making informed purchasing decisions. Sec-butyl disulfide, identified by CAS 5943-30-6, is no exception. As a vital organic intermediate, its performance in synthesis processes is directly linked to its quality and adherence to precise chemical and physical parameters. Knowing these specifications helps procurement managers and research scientists select the right product from a reputable supplier.

The most commonly cited specification for sec-butyl disulfide is its purity. Manufacturers typically offer this compound with a minimum purity of 98.5%. This high level of purity is crucial for ensuring predictable reaction kinetics and minimizing unwanted side reactions in complex organic synthesis. When you buy sec-butyl disulfide, always verify this purity percentage from the manufacturer's Certificate of Analysis (COA).

Beyond purity, the physical appearance is a key identifier. Sec-butyl disulfide is consistently described as a colorless liquid. Any deviation from this appearance could indicate contamination or degradation, underscoring the importance of sourcing from manufacturers who maintain stringent quality control throughout their production and packaging processes.

Key physical properties also play a role in its application and handling. Its molecular weight of approximately 176.36 g/mol (for C8H18S2) and density around 0.957 g/cm³ provide essential data for volumetric calculations and material handling. Understanding its boiling point (around 220.6°C) and flash point (around 67.2°C, closed cup) is vital for safe storage, transportation, and processing, particularly in industrial settings. Solubility is another critical factor; sec-butyl disulfide is noted as being soluble in ethanol and ether but insoluble in water, which influences its use in different solvent systems.

For those looking to purchase sec-butyl disulfide, these specifications are not merely data points; they are guarantees of performance. Engaging with a knowledgeable manufacturer or supplier in China, for instance, allows for easy access to this detailed information. It ensures that you are acquiring a product that meets industry standards and will perform reliably in your specific applications. Therefore, prioritizing suppliers who clearly communicate and consistently deliver on these specifications is a strategic move for any chemical business.
