Descripción general

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product is a bio-based ethanol and is aligned with the 5th principle of Green Chemistry "Safer Solvents and Auxiliaries" and 7th principle "Use of Renewable Feedstock".

Aplicación

Ethanol may be used as follows:

  • Preparation of PANI/MnFe2O4 nanocomposite thin films to study their optical properties and capacitive behaviors
  • Preparation of Andrographis paniculata extracts for HPLC fingerprint analysis to study their composition and biological activities
  • As a mobile phase for the HPLC separation of paritaprevir, ritonavir, and ombitasvir in pharmaceutical dosage forms
  • To evaluate the anti-solvent effects of three solvents in order to quantify the paracetamol active pharmaceutical ingredient (API) and its two impurities precipitating out during washing

Precaución

Pertains only in Germany: Nicht zu Fertigungszwecken1

Questions

1–2 of 2 Questions  

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

    1 answer

    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 answer

    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.
