1-methyl-4-nitrosopiperazine-d4 200μg/mL in Methanol

1-methyl-4-nitrosopiperazine-d4 (MNPA-d4) is a stable isotope-labeled derivative of 1-methyl-4-nitrosopiperazine, which is a potent mutagen and carcinogen found in tobacco smoke and other environmental sources. MNPA-d4 is commonly used as an internal standard for the quantification of MNPA in various biological samples using analytical techniques such as liquid chromatography-mass spectrometry (LC-MS). The usage of MNPA-d4 in methanol is primarily for analytical purposes. The compound is dissolved in methanol to create a stock solution of 200μg/mL, which can be further diluted to create calibration standards for LC-MS analysis. MNPA-d4 is added to biological samples along with the internal standard to enable the accurate quantification of MNPA levels. From a chemical perspective, MNPA-d4 is a labeled compound, which means that it contains four deuterium atoms at specific sites within the molecule. These deuterium atoms are added to the compound to provide a unique signature that can be easily distinguished from the non-labeled MNPA. The compound has a molecular weight of 197.3 g/mol and a chemical formula of C6H8D4N3O2. Overall, MNPA-d4 in methanol is a valuable tool for researchers and analytical chemists who are studying the effects of MNPA exposure on human health. By providing an accurate and precise method for quantifying MNPA levels in biological samples, MNPA-d4 can help to better understand the link between MNPA exposure and the development of cancer and other diseases.
