一般說明
还原铁粉，也称为海绵铁，是铁的细粉形态，常用于化学合成过程。它是在受控环境中通过还原铁氧化物制成的，通常使用氢气或一氧化碳气体作为还原剂。
在化学合成中，还原铁粉可以作为还原剂、催化剂或前体，广泛应用于各种反应。它常用于将有机官能团（如醛、酮和硝基化合物）转化为相应的还原形态。已知它还能促进氢化反应。
还原铁粉在铁基催化剂、磁性材料、颜料和金属合金的生产中都有应用。 它常用于药物合成、有机化学和工业制造。由于还原铁粉可能与水分和氧气发生反应，导致氧化并改变其性质，因此必须小心处理。应遵循适当的储存和处理程序，以维持品质并防止发生不良反应。

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.

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
