  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What is the molarity of Product A9967, Glacial acetic acid?

    Glacial acetic acid is 17.4 M.

  4. Product A9967, Glacial acetic acid, is a solid instead of a liquid. Is it ruined?

    The melting point of glacial acetic acid is approx. 16°C. So it may freeze in shipment (or storage in a cold place).  Simply leave it in a warm place and it will melt.  This does not affect product quality at all.

  5. Why is Product A9967 called glacial acetic acid?

    The term "glacial" indicates the product is anhydrous acetic acid rather than an acetic acid solution. When the anhydrous liquid freezes, it can look like glacial ice.
