N-Acetyl-d3-S-(N-methylcarbamoyl)-L-cysteine is a stable isotopically labeled internal standard used in quantitative mass spectrometry. It features deuterium substitution to ensure accurate analytical calibration without altering chemical behavior. The molecular formula is C6H10D3NO4S, and it serves as a critical reference for tracing metabolic pathways of N-acetylcysteine derivatives.
