Description
Glycerol is a pharmacopoeia-quality polyol excipient at approximately 86 % according to Ph. Eur., with CAS number 56-81-5 and empirical formula C₃H₈O₃. Supplied as a ROTIPHARM® excipient, it has molar mass 92,09 g/mol, density in the range 1,22 to 1,23 g/cm³, flash point 180 °C and boiling point 290 °C. The product is Typical applications include humectant and co-solvent roles, sample preparation and compounding where an aqueous glycerol grade is preferred. This material from manufacturer Carl ROTH provides clear identity data including EG nr. 200-289-5 alongside the stated assay and physical properties. Density and thermal data support predictable handling in controlled laboratory and production settings. The product forms part of the solvents in pharmacopoeia quality assortment and is chosen when workflows specify Ph. Eur. glycerol at approximately 86 % in a convenient one-litre plastic pack.
