2-Butanone, min. 99,5 %, VLSI Grade, 2.5 l, plastic

2-Butanone is a high-purity organic solvent of minimum 99.5 % VLSI Grade, with empirical formula C₄H₈O and CAS number 78-93-3. The compound exhibits a molar mass of 72.11 g/mol, density of 0.81 g/cm³, flash point of –8 °C and boiling range of 79 to 80 °C. Supplied in a 2.5 l plastic bottle, this grade satisfies stringent cleanliness demands typical of semiconductor processing and precision laboratory work. 2-Butanone (Carl ROTH) carries EG number 201-159-0 and UN number 1193, confirming its established chemical identity for regulated handling. The solvent serves cleaning, extraction and process-chemistry duties where low residue and tightly defined purity are essential. Its physical constants enable controlled use in ventilated laboratory environments and support reproducible process outcomes. The 2.5 litre plastic packaging offers a practical working volume for routine operations while preserving product integrity. Researchers and process chemists select this VLSI Grade material when consistent solvent performance and fully documented specifications are required for critical applications.
