Description

n-Acetyl-S-Propyl-L-Cysteine is a specialized derivative of the amino acid L-cysteine, featuring an acetyl group and a propyl thioether moiety. This molecular structure makes it a valuable intermediate and building block in advanced pharmaceutical synthesis and biochemical research. It is particularly sought after by manufacturers and R&D teams in the pharmaceutical, nutraceutical, and fine chemical sectors for developing novel compounds and studying metabolic pathways.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of more complex active pharmaceutical ingredients (APIs), particularly those targeting respiratory or metabolic conditions.
• Biochemical Research: Used as a substrate or reference standard in enzymatic studies and metabolic pathway research related to cysteine derivatives.
• Nutraceutical Development: Investigated for potential applications in advanced dietary supplements due to its role as a modified cysteine source.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in analytical laboratories.
• Fine Chemical Synthesis: Employed as a chiral building block for the asymmetric synthesis of complex organic molecules.

Quality Control

Our n-Acetyl-S-Propyl-L-Cysteine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting standards for research and production use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption. For long-term storage, consider using desiccants or storing under an inert atmosphere to minimize potential oxidation.
