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
Butylated hydroxytoluene (BHT) is a synthetic antioxidant commonly used in biologic formulations to prevent oxidative degradation. It acts as a preservative, protecting biologic products from oxidation, which can affect the potency and stability of sensitive molecules. Its application is critical in maintaining the integrity of biologics, particularly those that are exposed to air or light during production and storage.
The United States Pharmacopeia (USP) provides quality standards for biologics to ensure their safety, efficacy, and quality throughout the manufacturing process. These standards assist manufacturers in adhering to regulatory requirements and help safeguard public health by reducing risks associated with biologics.
Application
- Dutasterid- und Tamsulosinhydrochlorid-Kapseln

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
