Product Description

Product Introduction

1-Propanethiol (also called n-Propyl Mercaptan, CAS 107-03-9) is a primary aliphatic thiol with the formula C₃H₈S
It is a volatile, strongly odorous sulfur-containing liquid that is used as a chemical intermediate in organic synthesis, and also applied in thiol-based chemistry and research

Applications & Descriptions

  1. Organic Synthesis Intermediate
    Acts as a nucleophilic sulfur donor in the synthesis of thioethers, thioesters, and other sulfur-containing compounds

  2. Chemical Building Block for Thiol Chemistry
    Used to make more complex thiols, mercaptans, and sulfur-based functional molecules

  3. Flavor / Fragrance (Specialty)
    Though very pungent, it may be used in trace amounts in certain specialty fragrance or flavor formulations (but limited due to odor and toxicity)

  4. Research / Laboratory Reagent
    Useful in mechanistic studies, in the investigation of thiol reactivity, and as a reference in sulfur-organic research

  5. Corrosion / Metal Chemistry
    Employed as a ligand in coordination chemistry or in metal-sulfur systems, potentially as a capping or passivation agent
