Allopregnanolone-[d5] (Solution)

Allopregnanolone-[d5] (Solution) is a stable isotope-labeled solution of Allopregnanolone, a steroid hormone and a potent positive allosteric modulator of the GABA-A receptor. This compound is labeled with deuterium at the 5th position of the steroid ring, which makes it useful for metabolic and pharmacokinetic studies. Allopregnanolone-[d5] (Solution) has several applications in both research and clinical settings. It is commonly used as an internal standard in LC-MS/MS-based assays for the quantification of endogenous Allopregnanolone levels in biological samples. It can also be used to study the pharmacokinetics and metabolism of Allopregnanolone and its derivatives. The chemical formula of Allopregnanolone-[d5] is C21H29D5O2, and its molecular weight is 329.57 g/mol. It is a colorless, clear liquid that is soluble in organic solvents like methanol, ethanol, and dimethyl sulfoxide (DMSO). It should be stored in a cool and dry place, away from light and heat sources. In conclusion, Allopregnanolone-[d5] (Solution) is a useful tool for researchers and clinicians studying the pharmacokinetics and metabolism of Allopregnanolone. Its stable isotope labeling allows for accurate quantification and analysis of endogenous Allopregnanolone levels in biological samples.
