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.

Application
- SPECTROPHOTOMETRIC DETERMINATION OF THYMOL IN MOUTHWASHES VIA SODIUM NITROPRUSSIDE REACTION WITH HYDROXIDE AMINE HYDROCHLORIDE.: This study presents a spectrophotometric method for determining thymol in mouthwashes using a reaction with sodium nitroprusside and hydroxide amine hydrochloride. This analytical approach enhances the accuracy and reliability of thymol quantification in pharmaceutical products (International Journal of Research in Pharmacy and Chemistry, 2023).
- Efficacy of postharvest sodium nitroprusside application to extend storability by regulating physico-chemical quality of pear fruit.: This study investigates the application of sodium nitroprusside in extending the storability of pear fruits by regulating their physico-chemical quality. The findings suggest significant improvements in fruit preservation and quality maintenance during storage (Food Chemistry, 2021).

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.
