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.

Applicazioni
- Hydration structures of lactic acid: Research explored the hydration structures of lactic acid and characterized the ionic clathrate hydrate formed with a biological organic acid anion, utilizing Tetra-n-butylammonium hydroxide in this process (Muromachi et al., 2014).
- Protection of ribonucleosides in RNA synthesis: A study demonstrated the use of Tetra-n-butylammonium hydroxide in the solid-phase synthesis of RNA sequences, particularly for the protection of 2′-hydroxyl groups of ribonucleosides (Cieslak et al., 2013).
- Analysis of cosmetic products: Tetra-n-butylammonium hydroxide is used as a ion-pairing agent in the simultaneous analysis of various organic acids in cosmetic products by enhancing the extraction efficiency during high-performance liquid chromatography (Mikami et al., 2002).
- Determination of calcium dobesilate in human plasma: The compound was employed in the ion-pairing extraction and high-performance liquid chromatography for the determination of calcium dobesilate in human plasma, highlighting its utility in clinical analytical methods (Rona and Ary, 2001).

How can I determine the shelf life / expiration / retest date of this product?
1 risposta-
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.
