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.

Application
- Validation and application of an online extraction and liquid chromatography tandem mass spectrometry assay for the analysis of delamanid and its DM-6705 metabolite in human breast milk.: This study presents a validated method for analyzing delamanid and its metabolite in human breast milk, using ammonium carbonate in the sample processing phase. The technique offers a robust tool for therapeutic drug monitoring in breastfeeding mothers (Mkhize et al., 2024).
- Visualizing the Internal Nanocrystallinity of Calcite Due to Nonclassical Crystallization by 3D Coherent X-Ray Diffraction Imaging.: Research utilizing ammonium carbonate to influence the crystallization process of calcite, providing insights into the nonclassical pathways of nanocrystal formation and transformation in a controlled environment (Suzana et al., 2024).
- Ammonia measurement in human breath of subjects with Helicobacter pylori using photoacoustic spectroscopy.: This study details a method for detecting ammonia in the breath of patients infected with Helicobacter pylori, using ammonium carbonate as a calibration standard, which could lead to non-invasive diagnostic approaches (Popa et al., 2024).
- Determining Ultrasound Parameters for Bursting Polymer Microbubbles for Future Use in Spinal Cord Injury.: Discusses the development of ultrasound parameters for bursting polymer microbubbles encapsulating agents like ammonium carbonate, aimed at targeted therapies for spinal cord injuries (Oeffinger et al., 2024).

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
