Description
Dichloromethane is a chlorinated laboratory solvent in ROTIDRY® grade with a minimum purity of 99,8 % and a maximum water content of 50 ppm. It is identified by CAS number 75-09-2 and empirical formula CH₂Cl₂, with a molar mass of 84,93 g/mol, a density of 1,33 g/cm³ and a boiling point of 40 °C. The solvent is stabilised with amylene. Supplied in a 1 l glass bottle from manufacturer Carl ROTH, this low-water grade is intended for moisture-sensitive organic work, extractions and analytical sample preparation where residual water must stay tightly controlled. ROTIDRY® dichloromethane supports synthesis, work-up and chromatography steps that benefit from a dry, high-assay medium. Its convenient boiling point aids solvent removal after partitioning or reaction. Physical constants such as density and molar mass assist method setup and solvent exchange. Laboratories select this specification when reproducible dryness and consistent assay are required for routine and research applications. Standard laboratory precautions for halogenated solvents apply during handling and storage in ventilated areas.
