Descripción general

Ammonium acetate (NH4CH3CO2, NH4OAc) is a water-soluble, hygroscopic ammonium salt. It is an eco-friendly and inexpensive compound that can be prepared by reacting glacial acetic acid with ammonia or ammonium carbonate. It is used as a catalyst as well as a source of ammonia in organic synthesis.

Aplicación

Ammonium acetate can be used as a reactant as well as a catalyst in the synthesis of:      
  • 1,3-oxazine derivatives by three-component condensation reaction with 2-naphthol and aromatic aldehydes.      
  • Symmetrical terpyridine derivatives by treating with aromatic aldehydes and ethyl cyanoacetate.      
  • Isoquinolines, furopyridines, and thienopyridines via Pd-catalyzed sequential coupling-imination-annulation reactions of ortho-bromoarylaldehydes and terminal alkynes.

It can also be used as a nitrogen source to synthesize benzoxazole derivatives via multicomponent condensation reaction with catechols, and various aldehydes in the presence of Fe(III)−salen complex as a catalyst.

Características y beneficios

NH4OAc is an eco-friendly, shelf-stable, and safe reagent.

Preguntas

1–2 de 2 Preguntas  
  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 respuesta
    1. 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

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 respuesta
    1. 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.
