Aldosterone, the primary mineralocorticoid, is synthesized and secreted by the zona glomerulosa of the adrenal cortex in response to activation of the renin-angiotensin system or high dietary potassium.

Aldosterone (Standard) is a reference material suitable for analysis, typically used as a reference standard in research and analysis of Aldosterone (T19186). Aldosterone is the primary mineralocorticoid steroid, widely used in research, clinical testing, and laboratories for qualitative/quantitative analysis by liquid chromatography-tandem mass spectrometry (LC-MS/MS) or gas chromatography (GC). Aldosterone (Standard) serves as a reference standard for assessing adrenocortical function, blood pressure regulation, and diseases such as primary/secondary hyperaldosteronism, typically provided in acetonitrile as a solvent.
