Methyl Propyl Sulfide (CAS 3877-15-4) is an organosulfur compound that holds significant utility across various industrial sectors, most notably in the flavor and fragrance industries. As a dedicated manufacturer and supplier, we are committed to providing high-purity Methyl Propyl Sulfide that meets the exacting demands of these applications. This article delves into its key properties and industrial relevance.

Chemically, Methyl Propyl Sulfide, with the molecular formula C4H10S and a molecular weight of approximately 90.19 g/mol, is characterized by the presence of a sulfur atom linking a methyl group and a propyl group. Its physical state is a clear, colorless liquid, with a distinctive aroma profile described as alliaceous, creamy, and green leek. This unique sensory characteristic is precisely why it is sought after in flavor and fragrance formulations.

Key physical properties include a boiling point of around 95.5 °C, a melting point of -113 °C, and a density of 0.842 g/mL at 25 °C. The flash point of 63 °F indicates its flammability, necessitating appropriate handling and storage procedures. Its refractive index is approximately n20/D 1.4430.

In terms of industrial applications, Methyl Propyl Sulfide serves as a crucial flavor ingredient, contributing savory and pungent notes to food products such as soups, sauces, and processed meats. In the fragrance sector, it can add complexity and earthy nuances to perfumes and other scented products. Beyond its organoleptic properties, it also finds use as a chemical intermediate in organic synthesis and as a research chemical.
