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.

Anwendung
- beta-lactoglobulin stabilized nanemulsions--Formulation and process factors affecting droplet size and nanoemulsion stability.: This study investigates the impact of formulation and process parameters on the stability and size of beta-lactoglobulin stabilized nanemulsions, potentially involving potassium phosphate dibasic in the formulation process (Ali et al., 2016).
- Correlation of characteristics of gel extrusion module (GEM) tablet formulation and drug dissolution rate.: Examines how the characteristics of gel extrusion in tablet formulations influence drug dissolution rates, relevant for chemists looking into dissolution behavior and possibly involving potassium phosphate dibasic (Juang and Storey, 2003).
- High-performance liquid chromatographic determination of phenylureas by photochemically-induced fluorescence detection.: Discusses a method for detecting phenylureas using high-performance liquid chromatography, which could involve potassium phosphate dibasic as a component of the mobile phase or sample preparation (Munoz de la Pena et al., 2002).
- Assay and purity analysis of diatrizoate sodium in drug product by LC.: This research details a method for assaying and analyzing the purity of diatrizoate sodium, where potassium phosphate dibasic could be part of the chromatographic system (Chellquist et al., 1997).

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.
