If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

General description
Application
- Characterization of the aroma-active compounds in Xiaokeng green tea by three pretreatment methods combined with gas chromatography-olfactometry (GC-O).: This study identified and characterized the aroma-active compounds in Xiaokeng green tea, highlighting the significant role of dimethyl sulfide as a contributor to its unique aroma profile (Gan et al., 2024).
- Novel insights into dimethylsulfoniopropionate cleavage by deep subseafloor fungi.: This article provides new insights into the metabolic pathways of deep-sea fungi, focusing on the cleavage of dimethylsulfoniopropionate (DMSP) and subsequent production of dimethyl sulfide, impacting sulfur cycling in marine ecosystems (Liu et al., 2024).
- Adsorption Mechanism and Regeneration Performance of Calcined Zeolites for Hydrogen Sulfide and Its Application.: The study explores the use of calcined zeolites for the adsorption of hydrogen sulfide, a precursor to dimethyl sulfide, and discusses the material′s regeneration performance for industrial applications (Zha et al., 2024).

How can I determine the shelf life / expiration / retest date of this product?

Many articles on line seem to imply that dimethyl sulphide ONLY originates from the metabolism of certain microrganisms, and I would like to know if that is accurate.
1 respuesta-
Dimethyl sulfide can be produced through chemical synthesis by treating hydrogen sulfide with excess methanol over an aluminum oxide catalyst.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 respuesta-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
