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.

应用
- 乳酸的水合结构：研究探索了乳酸的水合结构，并利用四正丁基氢氧化铵表征了与生物有机酸阴离子形成的离子包合物水合物（Muromachi et al., 2014).
- 核糖核苷在RNA合成中的保护作用：一项研究表明，四正丁基氢氧化铵可用于RNA序列的固相合成，尤其可用于核糖核苷2-羟基的保护（Cieslak et al., 2013).
- 化妆品分析：四正丁基氢氧化铵可用作离子对试剂，用于同时分析化妆品中的各种有机酸，提高高效液相色谱中的提取效率(Mikami et al., 2002).
- 人血浆中羟苯磺酸钙的测定：该化合物可用于离子对萃取和高效液相色谱法，用于测定人血浆中的羟苯磺酸钙，研究体现了其在临床分析方法中的实用性(Rona and Ary, 2001).

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