        ||       ||  

        O        O  

• Comprises a linear 6-carbon chain (adipate backbone) with a methyl ester group (–COOCH₃) at each end.

  Systematic Name: Dimethyl hexanedioate

  CAS Number: 627-93-0

  Key Properties:

• Physical State: Colorless to pale yellow liquid.

• Odor: Mild, characteristic ester odor.

• Solubility: Low in water; miscible with common organic solvents (ethanol, ether).

• Boiling Point: ~115 °C (10 mmHg), ~245 °C (760 mmHg).

• Density: ~1.05 g/cm³.

  Reactivity & Uses:

• Solvent: Used in coatings, resins, and cleaning products due to low toxicity, biodegradability, and high solvency power.

• Chemical Intermediate: Precursor for synthesizing polyesters, plasticizers (e.g., via transesterification to longer-chain esters), adhesives, and lubricants.

• "Green" Reagent: Valued as a safer, renewable alternative to volatile/hazardous solvents (e.g., in decaffeination).

• Monomer: Participates in polycondensation reactions to form polyesters.

  Safety: Generally low toxicity (LD50 ~5g/kg oral/rat), mild irritant. Considered environmentally friendlier than many solvents/plasticizers.

In essence: Dimethyl adipate is a linear aliphatic diester primarily used as a biodegradable solvent and versatile intermediate in polymer/chemical synthesis, offering a more sustainable profile.
