General description

Benedict′s reagents comprise of copper sulphate, sodium carbonate which functions as a mild alkali, and sodium citrate. It is quite stable. On boiling this reagent with glucose, it gives a white precipitate of cuprous thiocyanate. It is primarily used for the estimation of glucose in urine.[1]

Application

Benedict′s reagent may be used during TLC analysis of mesocotyl methanol extracts during a study to evaluate sorghum resistance associated with accumulation of undetected toxic host metabolites.[2] It may also be also be used to synthesize an SEM image of the cubic shaped Cu2O with smooth surface.[3]

Other Notes

Reagent used for the detection of reducing sugars and other reducing substances; detection limit: 0.01 % glucose in water[4]

Questions

1–2 of 2 Questions  
  1. 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.

  2. 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
