Stearic acid butyl ester, for synthesis, 100 ml, glass

Stearic acid butyl ester is a long-chain fatty acid ester supplied for synthesis, with the empirical formula C₂₂H₄₄O₂ and CAS number 123-95-5. Key physical data include a molar mass of 340,60 g/mol, a density of 0,86 g/cm³, a boiling point of 343 °C, and a flash point of 160 °C. Its defined identity under EG number 204-666-5 supports reproducible process design and documentation in academic and industrial laboratories. The material from manufacturer Carl ROTH provides a practical butyl stearate building block for studies of esterification, plasticiser-related investigations, and development of lipophilic mixtures. Liquid presentation in a one-litre glass container allows convenient dispensing across multi-step synthetic sequences and repeated trials. Clear molar mass and density values help with stoichiometric calculations and solvent-system planning. Chemists seeking a synthesis-grade stearic acid butyl ester will find this pack size appropriate for both method scouting and routine preparative use.
