CAS Number: 8032-32-4 MDL No.: MFCD00081849 Boiling Point: 30-60 C(lit.); 35-60 C Density: 0.64 g/mL at 25 C(lit.) Refractive Index: n20/D 1.363(lit.) EC Number: 232-453-7 UNSPSC Code: 12190000 General description: Petroleum ether is a mixture of low boiling aliphatic hydrocarbons (mainly hexane and pentane) that is generally used as a laboratory solvent. General description: Petroleum ether is a colorless liquid. Extracts of leaves of Litchi chinensis Gaertn. (Sapindaceae) have been prepared in petroleum ether and were evaluated for antiinflammatory, analgesic and antipyretic activities. Pentanes and hexanes are the major constituents of petroleum ether. Application: Petroleum ether has been used for the analysis of total dietary fiber content by employing a total dietary fibre assay kit. It may be used in the absorption chromatographic purification of organic compounds.

ACS reagent, ≥98.5% Synonym(s): Hexanes; Isohexane Empirical Formula: C₆H₁₄ Formula Weight: 86.18 Linear Formula: C₆H₁₄ MDL Number: MFCD02179311 Purity: ≥98.5% Boiling Point: 68-70 °C(lit.) Melting Point: −95 °C(lit.) Density: 0.672 g/mL at 25 °C(lit.) Refractive Index: n 20/D 1.379(lit.) Beilstein Registry Number: 1730733 RIDADR: UN 1208 3 / PGII Application Hexane (n-hexane) has been used in the preparation of precursor required for the synthesis of chiral stationary phase (IMPCSP). IMPCSP was employed for the enantioseparation of racemic drugs by high-performance liquid chromatography (HPLC) and supercritical fluid chromatography (SFC). It may be used as a carrier phase for microfluidic devices. General description The product is a mixture of hexane isomers and methylcyclopentane. Hexane (mixture of isomers) can be isolated from petroleum by distillation or by cracking. They form major constituents of petroleum ether. It is a non-renewable organic solvent mainly used for the dissolution and extraction of oils and fats. Separation of the isomeric forms of hexane on the basis of degree of branching using Fe2(BDP)3 (BDP2- = 1,4-benzenedipyrazolate) has been reported.
