General description

Dichloromethane (DCM) is a chlorinated organic solvent with a wide range of industrial applications and organic syntheses. It has a low boiling point, high density and is immiscible in water. DCM is susceptible to degradation with time, which can be suppressed by adding amylene as a stabilizer.

Application

Dichloromethane
  • Organic synthesis
a) Dakin, Dess-Martin and Ley Oxidation
b) Enyne metathesis, widely used catalyst is the Grubbs′s second-generation ruthenium complex
c) Jacobsen-Katsuki epoxidation
d) Boc-deprotection of immobilized Boc-NH2-poly(ethylene glycol)-plasma layers
e) Can react with phosphines or amines in the formation of the corresponding alkylated products
  • Adhesive and paint formulation
  • Extraction-concentration analysis
  • Flash chromatograph
  • Electronic industry in printed circuits board
  • Production of cellulose triacetate

Packaging

500 mL in glass bottle
1, 6×1, 2.5, 4, 4×4 L in glass bottle
18, 20 L in steel drum
200 L in Pure-Pac™ 2
200 L in steel drum

Features and Benefits

ACS solvents meet or exceed the high standards of the American Chemical Society (ACS), with test specifications that are specialized to every compound. According to the American Chemical Society, ACS reagent grade implies that it is a substance of sufficient purity to be used in most chemical analyses or reactions
