Applicazioni
D-Gluconic acid is a non-volatile, organic acid generally used as a sequestering agent and as a scale inhibitor.[1] Due to its tendency to chelate with earth alkaline elements and heavy metals, it is also used as a metal extractant.[1] Gluconic acid and its salts are
used in hygienic products, food and pharmaceutical industry.[2]

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

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.

Hi what is the molarity of the solution provided? 25g in 50%wt solution
1 answer-
At exactly 50% the molarity of this solution is 3.14M. The molarity may be calculated using the following equation below:
Molarity (moles/L) = Density (g/L) ÷ Molecular Weight (g/mol) * purity
= 1234g/L ÷ 196.16 g/mol * 0.50
= 3.14539MThe concentration of this product ranges from 49 - 53% and may change slightly from lot to lot. Please see the link below to access a sample or specific lot Certificate of Analysis:
