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

is this curcumin nanoparticle?
1 answer-
The product is specified to be a 'powder' but the particle size is not characterized. It is likely more on the order of microns than nanometers, but it can't be guaranteed either way.

What are the recommended methods for dissolving curcumin powder (C1386)?
1 answer-
Dissolving curcumin (product C1386) can be challenging. Below are some recommendations for preparing standard solutions:
• Ethanol: 10mg/mL
• DMSO: >11 mg/mL (according to available literature)
• 0.5 M NaOH: Soluble (then immediately dilute in PBS according to literature)
Additionally, here are two methods that might be helpful:
Method 1: Use DMSO to create a stock solution at 1000 times the working concentration of curcumin.Helpful?

Hello, I am currently looking for curcumin powder that I can use as a standard for UV spectrophotometer quantification. What is the difference between the product that is offered here compared to 08511-10 MG Curcumin product?
1 answer-
Both items are research grade products. Product 08511 is assigned a minimum purity specification of 98% and is tested for use as an an analytical standard in HPLC and GC. The C1386 is assigned a minimum purity specification of 65% and is not tested for any specific application. The major differences will lie in the purity and testing for each product. Please see the sample Certificate of Analysis for both items:
