General description
Acetic acid is an aliphatic organic acid. It is a hygroscopic, corrosive liquid with a vinegar-like odor. It can be synthesized by oxidizing acetaldehyde in the presence of manganese or cobalt salts. It is utilized for synthesizing acetic anhydride, cellulose acetate and acetic esters. Its impact on the degradation of historic paper has been analyzed.
Application
Acetic acid (AcOH) can be used as:
Acetic acid can also be used in the following:
- A reaction solvent in many organic reactions such as bromination, hydrolysis, solvolysis, reductions, and hydrogenations.
- A reagent in the protonolysis of organometallic compounds.
- An acetylating agent for the acetylation of electron-rich aromatic compounds.
- A catalyst to synthesize di(indolyl)methanes by the condensation reaction of indole and aromatic aldehydes.
- A solvent system to prepare 3,4-dihydropyrimidin-2(1H)-one derivative via Biginelli reaction of aromatic aldehydes, 1,3-dicarbonyl compounds, and urea in the presence of a boric acid catalyst.
Acetic acid can also be used in the following:
- Manganese(III) acetate/AcOH catalytic system is used in the conversion of alkenes to lactones.
- Iron salts/AcOH is used to oxidize 2-methylnaphthalene to 2-methyl-1-naphthol in the presence of H2O2.
Features and Benefits
- Good stability towards many reagents
- Excellent solubility of organic compounds in this reagent

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
