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 回答-
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 is Product P2297, Picrylsulfonic acid solution, tested? Do you have any references for its use besides Sigma's method?
1 回答-
Sigma's suitability assay is based on a published method.1 We use a 500-fold dilution as a working solution, with glycine as a standard. Hydrochloric acid is used to stop the reaction, and to reduce yellow background due to picric acid. Sodium phosphate is used as a buffer in place of sodium bicarbonate to avoid formation of CO2 when HCl is added. Absorbance is read at 420 nm.Other procedures have been published. For example:---Twenty-five mL of 0.03 M TNBS is added to 1 mL of sample (in borate buffer), agitated to ensure complete mixing, and allowed to stand for 30 minutes at room temperature (25±1°C). No quenching step is used. In the blank, buffer replaces sample. Absorbance is read at 420 nm.2---Protocols using a more concentrated solution of picric acid (1.1 M) have been published.3Note: TNBS forms an orange complex with amines, monitored at 420 nm, but the EmM of the complexes will vary with the reacting group: for alpha-amino groups, 22.0; for epsilon-amino groups, somewhat lower; and for thiol groups, 2.25.3References:1.

Is Product P2297, Picrylsulfonic acid solution, considered to be stable?
1 回答-
It is explosive when it is dry. The solution should be stored at 2-8°C in the dark. Under these conditions less than 5% decomposition will occur over five months. At 37°C, 50% decomposition occurred in 60 days. Picrylsulfonic acid decomposes to picric acid, crystals of which may form in the solution, but this impurity causes no interference in usage. The solution may also contain a trace amount of 2,4-dinitrophenol (typically °C may enhance shelf-life of stock solutions.
