一般描述

邻甲苯磺酰胺是含有糖精的人造甜味物质中的一种主要杂质[1]。 已报道可通过反相HPLC方法测定糖精和糖精钠中的邻甲苯磺酰胺[2]。

应用

  • 铑钳形复合物的动态配体反应性：讨论邻甲苯磺酰胺作为配体在高级化学合成中的作用，证明它在为催化过程创建反应中间体方面的实用性（Tang et al., 2015）。
  • 电喷雾电离质谱法中芳离子与碰撞气体N2的反应：强调邻甲苯磺酰胺在质谱研究中的使用，以了解电离机制，有助于识别复杂的化学结构（Liang et al., 2015）。
  • 废水中的苯并磺胺:方法发展、发生和去除效率：关注从废水中检测和去除邻甲苯磺酰胺的方法，强调其普遍存在以及与消除其相关的挑战（Ajibola et al., 2015）。

Questions

1–2 of 2 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. 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

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

    1 answer

    1. 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.
