Description

n-(Acetyl-D3)-S-Allyl-L-Cysteine is a stable isotope-labeled derivative of S-allyl-L-cysteine, a key bioactive organosulfur compound found in garlic. This deuterated analog is specifically designed for use as an internal standard in quantitative analytical methods, providing unmatched accuracy and reliability for researchers. It is an essential tool for scientists in pharmaceutical development, clinical research, and nutritional biochemistry who require precise measurement of sulfur-containing metabolites and their pharmacokinetics.

Application

• Quantitative Bioanalysis: Serves as a critical internal standard in LC-MS/MS and GC-MS assays for the accurate quantification of S-allyl-L-cysteine and related metabolites in biological matrices (plasma, serum, urine).
• Pharmacokinetic & Metabolic Studies: Enables precise tracking of absorption, distribution, metabolism, and excretion (ADME) of garlic-derived sulfur compounds in preclinical and clinical research.
• Nutritional & Dietary Supplement Research: Used to validate the bioavailability and bioactivity of active components in garlic extracts and formulated supplements.
• Drug Development: Supports the development of sulfur-containing drug candidates by providing a reliable reference for stability testing and metabolite profiling.
• Quality Control & Standardization: Essential for certifying the potency and consistency of garlic-based raw materials and finished products in GMP environments.
