Description

5-(Methylthio)-2-[(Methylthio)Methyl]Pent-2-Enal is a sulfur-containing aldehyde compound with a distinctive chemical structure that makes it a valuable intermediate and flavor/fragrance ingredient. This compound matters for its ability to impart unique savory, meaty, or roasted notes, making it highly sought after in the creation of complex flavor profiles. Industries that need this specialized chemical include flavor and fragrance manufacturing, food technology, and advanced organic synthesis for pharmaceuticals or agrochemicals.

Application

• Flavor and Fragrance Industry: A key intermediate for synthesizing complex sulfur-containing flavor compounds that replicate meaty, savory, roasted, or alliaceous (garlic/onion) notes in processed foods, savory snacks, and seasonings.
• Food Technology: Used in the development of reaction flavors and process flavors, particularly for creating authentic meat, poultry, and savory taste profiles in vegetarian and vegan food products.
• Organic Synthesis: Serves as a versatile building block in pharmaceutical research and agrochemical synthesis, where its reactive aldehyde and thioether groups can be modified to create novel molecules.
• Aroma Chemicals: Employed in the formulation of high-end perfumes and fragrances to add depth, complexity, and unique sulfurous nuances to fragrance compositions.
• Research & Development: Utilized in academic and industrial R&D laboratories as a reference standard or starting material for studying sulfur chemistry and developing new synthetic methodologies.

Quality Control

Our 5-(Methylthio)-2-[(Methylthio)Methyl]Pent-2-Enal is produced under strict quality management systems to ensure batch-to-batch consistency and purity suitable for flavor, fragrance, and synthesis applications. Quality is verified through comprehensive analytical techniques including GC, HPLC, and NMR spectroscopy. A Certificate of Analysis (COA) detailing identity, purity, and specific impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to maximize stability and shelf life. Keep away from strong oxidizing agents, strong bases, and heat sources. Due to its reactive aldehyde group and potential sensitivity, it is recommended to store under an inert atmosphere for long-term storage.
