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
Com seu alto grau de transmitância UV, baixa contagem de partículas, baixa acidez e alcalinidade, além de baixo nível de resíduos de evaporação, os solventes LiChrosolv são ideais para separações reprodutíveis. Como as separações normalmente ocorrem em condições de gradiente na HPLC analítica, oferecemos solventes de “grau de gradiente”, bem como de “grau isocrático”. Isso pode minimizar o efeito de gradiente do solvente envolvido.
Application
- para preparar soluções-estoque padrão e de trabalho de fenpropatrina e bifenretrina.
- em solventes alternativos e sustentáveis para química analítica verde.

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
