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.

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

What is the molecular weight of PTAA with product no. 702471? and how much-optimized quality of this product is needed in one milliliter of solvent (Toluene) to coat it as a Hole transporting layer for perovskite solar cells. share some PSCs articles.
1 risposta-
The number molecular weight is reported in the lot-specific Certificate of Analysis. Please access the link below to review a sample or lot specific Certificate:
https://www.sigmaaldrich.com/product/aldrich/702471#product-documentationThe average molecular weight of this material is not reported. However, historical data indicates a range of 17,000 - 20,000 g/mol.
Unfortunately, the concentration of PTAA in toluene for Hole transporting layer coating is not tested. Here is a review paper as a reference:
