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
Going beyond its solvent capabilities, propylene glycol excels as an excipient in pharmaceutical formulations, enhancing the solubility and stability of therapeutic molecules and pharmaceutical additives. This attribute proves indispensable in excipient and drug delivery research, contributing to the development of more efficacious and stable medications. In biochemical and physiological research, propylene glycol functions as a potent cryoprotectant, safeguarding cells and tissues from freezing-induced damage. Its application extends to investigations of drug absorption, metabolism, and distribution, providing researchers with a crucial tool to decipher the intricate journey of drugs within the body.
The versatility of propylene glycol extends to molecular biology, particularly in Polymerase Chain Reaction (PCR), where it safeguards DNA and RNA strands, ensuring reliable and reproducible results. Studies demonstrate its exceptional ability to stabilize DNA for extended periods, making it an essential component for long-term sample preservation in genetic and genomic analyses. In the pharmaceutical industry, propylene glycol finds extensive use as a solvent and extraction medium, playing a pivotal role in drug development research, facilitating efficient extraction and purification of bioactive compounds.

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
