For professionals in analytical chemistry, sourcing high-quality reference standards is paramount. Octadecane (CAS 593-45-3), a saturated C18 alkane, is a frequently used compound, particularly in gas chromatography (GC) and liquid chromatography (LC). As a dedicated supplier and manufacturer of specialty chemicals, we understand the critical requirements for purity and consistency that R&D scientists and procurement managers demand. This guide will help you understand why Octadecane is essential for your laboratory and how to efficiently purchase it from a trusted source.

Octadecane, often referred to as n-octadecane, is a straight-chain hydrocarbon characterized by its molecular formula C18H38. Its physical appearance is typically a white crystal, with a melting point around 28-30°C and a boiling point of approximately 317°C. This specific set of physical properties makes it an excellent candidate for various analytical applications. For instance, its predictable behavior under chromatographic conditions allows it to serve as a reliable calibrant or internal standard.

In gas chromatography, Octadecane can be used to determine column efficiency, calibrate retention times, or as a component in mixed standards for analyzing complex hydrocarbon mixtures. Its non-polar nature ensures good separation characteristics with non-polar stationary phases. For procurement managers looking to buy Octadecane, understanding the required purity is key. We offer various grades, ensuring that whether you need it for routine analysis or specialized research, you can find the right product. The price of Octadecane can vary based on purity and quantity, so it's advisable to request a quote for your specific needs.

Beyond its analytical roles, Octadecane has industrial applications, including in lubricants and as a phase change material. However, for laboratory use, its primary value lies in its role as a precise reference standard.
