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

What is the difference between Hydrazine hydrate product numbers 225819, 215155 and 207942?
1 answer-
Prod. No. 215155 is anhydrous hydrazine. There is no water associated with this product. It has a molecular (formula) weight of 32.05. Prod. No. 207942 is hydrazine monohydrate. There is one mole of water for every mole of hydrazine. It has a molecular (formula) weight of 50.06. Prod. No. 225819 is hydrazine hydrate. The hydrazine content by weight from batch to batch may vary between 50 to 60%. Because the amount of water present (the other 40 to 50%) will also vary from batch to batch, it does not have a defined molecular (formula) weight. If a batch was found to contain 54 wt% hydrazine, then that batch would have 1.5 moles of water for every mole of hydrazine.
