About 1,2-Propanedithiol, 95%

1,2-Propanedithiol is a phase transfer catalyst (Synthesis grade) carrying the CAS registry number 814-67-5, specified at 95% purity. With the molecular formula C3H8S2, it has a molar mass of 108.23 g/mol. The IUPAC name is propane-1,2-dithiol. It is also known as 1,2-Dimercaptopropane or Propylenedithiol.

The material typically appears as a colourless liquid. Keep containers tightly closed in a cool, well-ventilated area away from heat and ignition sources. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for phase-transfer catalysis, biphasic reactions, ion-pair extraction and food and flavour applications. It is used across academic and industrial research and food and beverage processing.

Vaqora Chemicals supplies 1,2-Propanedithiol in 5 mL, 10 mL and 1 L packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
