Product Overview
Description:
Spironolactone-d3 is a deuterated internal standard tailored for the mass spectrometry-based quantification (GC- or LC-MS) of spironolactone, a classic steroidal mineralocorticoid receptor antagonist. This steroid derivative displays high target selectivity for the mineralocorticoid receptor over the glucocorticoid receptor, while maintaining minor binding affinities for the androgen and progesterone receptors.
Labeling:
Stable isotope-labeled
Synonyms:
(7α,17α)-7-(acetylthio-d3)-17-hydroxy-3-oxo-pregn-4-ene-21-carboxylic acid-γ-lactone; SC-9420-d3
Formula:
C24H29D3O4S
Formula Weight:
419.6
Specification
Solubility in DMSO:
Soluble
Solubility in Other Solvents:
Soluble in acetonitrile and methanol.
Storage:
Storage at -20°C.
Applications:
Spironolactone-d3 functions as a stable isotope-labeled analytical standard for quantitative steroid-related LC-MS/MS workflows, supporting calibration, recovery assessment, and accurate compound measurement.
