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

It is 80% of hydrazine hydroxide in water (about 52% of hydrazine in water) or 80% of hydrazine in water. There is no MW on page. I thought that is less than 1 molecule of water to 1 molecule of hydrazine (sth like hydrazine half-hydrate).
1 answer-
It is the former. Product 8.04604 is approximately 80 percent hydrazine hydrate by weight, which corresponds to 51.2 percent hydrazine by weight. Based on a density of 1.02 g/mL for this solution, which is 51.2 percent hydrazine, and a molecular weight of 32.05 for hydrazine (N2H4), the molarity of this solution is approximately 16 M.
