How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
Aldrich Products
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
Not Finding What You Are Looking For?
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.

What is the difference between Hydrazine hydrate product numbers 225819, 215155 and 207942?
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.
Is Product 225819, Hydrazine hydrate, a liquid or a solid?
The package sizes for this product are in a mass unit (gram) rather than a volume unit (mL). However, this product is a liquid and not a solid. It has a reported density of 1.029 g/mL at 25°C.
