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.

Application
- Green Synthesis of the Flavor Esters with a Marine Candida parapsilosis Esterase Expressed in Saccharomyces cerevisiae.: This study demonstrates a green synthesis approach using a marine esterase for the production of flavor esters, including isobutyl acetate. The process employs Saccharomyces cerevisiae, showcasing the potential for sustainable production of flavoring agents in the food and beverage industry (Xue et al., 2020).
- In-line reaction monitoring of entacapone synthesis by Raman spectroscopy and multivariate analysis.: This research employs Raman spectroscopy to monitor the synthesis of entacapone in real-time. Isobutyl acetate is utilized as a solvent in the reaction, highlighting its relevance in pharmaceutical synthesis and process monitoring (Novak et al., 2011).
- Paint thinner exposure inhibits testosterone synthesis and secretion in a reversible manner in the rat.: This study investigates the effects of paint thinner exposure, which contains isobutyl acetate, on testosterone synthesis in rats. The findings provide insights into the potential endocrine-disrupting properties of isobutyl acetate in industrial applications (Yilmaz et al., 2006).
- Preparation of spherically agglomerated crystals of aminophylline.: This research explores the preparation of aminophylline crystals using isobutyl acetate as a solvent. The study emphasizes the compound′s utility in pharmaceutical formulations to enhance drug solubility and bioavailability (Kawashima et al., 1984).

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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
