Description

n-Acetyl-S-(3-Carboxy-1-Methylpropyl)-L-Cysteine, Disodium Salt is a high-purity, synthetically derived biochemical reagent, specifically a disodium salt derivative of a modified L-cysteine amino acid. This compound is of significant value in advanced research and development, particularly for its role as a key metabolite or analytical standard in biochemical and toxicological studies. It is primarily needed by pharmaceutical R&D laboratories, contract research organizations (CROs), and academic institutions focused on metabolism, biomarker discovery, and analytical method development.

Application

• Biochemical Research Standard: Serves as a certified reference material (CRM) or high-purity standard for quantitative analysis in mass spectrometry (LC-MS/MS) and HPLC.
• Metabolite Studies: Used in the investigation of metabolic pathways, specifically as a marker or intermediate in the study of cysteine-conjugate metabolism.
• Toxicology and Biomarker Research: Employed as a precise analytical standard for identifying and quantifying specific metabolites in biological samples for toxicological assessments.
• Pharmaceutical Development: Acts as a critical reagent in the development and validation of bioanalytical assays for drug metabolism and pharmacokinetics (DMPK) studies.
• Proteomics and Peptide Chemistry: May be utilized as a specialized building block or modifier in peptide synthesis research due to its protected cysteine moiety.
