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.

Descrizione generale
It is provided with a comprehensive certificate of analysis (CoA) containing a certified purity value, calculated by the mass balance approach. All information regarding the use of this CRM can be found on the certificate of analysis.N-Nitrosodimethylamine (NDMA) is a nitrosamine that occurs as an impurity in sartan angiotensin II receptor blocker drugs.
Applicazioni
- Determination of N-Nitrosodimethylamine (NDMA) as an impurity in four valsartan APIs and tablets by high-performance liquid chromatography (HPLC)
- Quantitative analysis of NDMA in valsartan pharmaceutical formulations by capillary electrophoresis-nanospray-mass spectrometry
- Simultaneous determination of N-nitrosodimethylamine and N-nitrosomethylethylamine in drug substances and products containing sartans, ranitidine, and metformin by solid-phase extraction (SPE) and gas chromatography-tandem mass spectrometry (GC-MS/MS)
- Analysis of NDMA in the olmesartan API and tablets by high-performance liquid chromatography-mass spectrometry (HPLC-MS)
- Development and validation of an HPLC-MS/MS method for separation and quantification of NDMA impurity for quality control of ranitidine products

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
