Isostearyl alcohol, min. 95 %, 500 g

Isostearyl alcohol is a long-chain fatty alcohol supplied at a minimum purity of 95 % for laboratory chemical work. It is registered under CAS number 27458-93-1, has the empirical formula C₁₈H₃₈O, and a molar mass of 270,49 g/mol. A density of 0,836 g/cm³ is stated, giving a useful physical reference for handling, formulation trials, and volume-related calculations. This variant comes in a 500 g pack size, suited to extended laboratory use, process development, and applications that require a larger working quantity of a C₁₈ fatty alcohol. The material is offered from manufacturer Carl ROTH within a biochemicals and fine-chemicals selection for professional users. Minimum 95 % purity supports consistent specification where isostearyl alcohol is called for in synthetic, analytical, or materials-oriented experiments. Laboratories can rely on CAS 27458-93-1 together with the empirical formula C₁₈H₃₈O for unambiguous identification in inventories and protocols. Molar mass 270,49 g/mol and density 0,836 g/cm³ assist stoichiometric and physical-property calculations during method design. Packaged as 500 g, this isostearyl alcohol grade provides a practical balance between availability and controlled consumption in research and development settings.
