Description

2-Pentanethiol is a versatile organic sulfur compound, also known as amyl mercaptan, with the CAS registry number 2084-19-7. This chemical is valued for its strong, distinctive odor and its role as a key intermediate and additive in various industrial synthesis processes. It is primarily utilized in the production of specialty chemicals, as a flavor/fragrance component, and in the polymer industry. Industries requiring sulfur-containing building blocks for pharmaceuticals, agrochemicals, or material science will find this a critical reagent.

Application

• Chemical Synthesis Intermediate: Serves as a crucial building block for synthesizing more complex sulfur-containing compounds in pharmaceuticals and agrochemicals.
• Flavor and Fragrance Industry: Used in trace amounts to impart sulfurous, alliaceous, or meaty notes in flavor formulations and fragrance compositions.
• Polymer Modification: Acts as a chain transfer agent or cross-linking agent in the production and modification of synthetic rubbers and polymers.
• Organic Synthesis Reagent: Employed in various organic reactions, including nucleophilic substitutions and additions, to introduce the pentylthio functional group.
• Gas Odorant: Due to its potent smell, it can be used as a stenching agent for safety in otherwise odorless fuel gases or chemicals.
• Research & Development: Utilized in laboratories as a standard or reagent for method development and chemical research.

Quality Control

Our 2-Pentanethiol is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC and NMR to verify identity and assay. A Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with every shipment, ensuring full traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and moisture ingress. Recommended storage temperature: 2-8°C.
