Dichloromethane (CH2Cl2, CAS 75-09-2) is a versatile solvent widely used in gas chromatography (GC) for sample preparation, extraction, and as a sample injection solvent due to its low viscosity and fast evaporation. Beyond the laboratory, it is used industrially as a paint stripper, metal degreaser, extraction solvent such as for decaffeinating coffee and tea, and blowing agent for polyurethane foam. It is also employed in analytical chemistry and industrial processes. This high-purity grade meets strict requirements for GC applications, ensuring reliable results. Key specifications include a molecular weight of 84.93 g/mol, stable storage at ambient conditions, and a signal word classification of "Warning" for safety. Molekula supplies Dichloromethane for GC from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
