Description

N,n-Diacetylcysteine is a chemically modified derivative of the amino acid L-cysteine, offering enhanced stability and bioavailability. This compound is of significant interest for its role as a versatile intermediate and a precursor for synthesizing advanced pharmaceutical and nutraceutical agents. It is primarily sought by manufacturers in the pharmaceutical, research, and fine chemical sectors for applications requiring a protected or more lipophilic form of cysteine.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of more complex active pharmaceutical ingredients (APIs) and prodrugs.
• Research Chemical: Used in biochemical and pharmacological research to study cysteine-related pathways, oxidative stress, and cellular protection mechanisms.
• Nutraceutical Precursor: Serves as a precursor in the development of advanced dietary supplements and health products.
• Antioxidant Studies: Employed in scientific studies to investigate novel antioxidant compounds and their mechanisms of action.
• Fine Chemical Synthesis: Utilized in organic synthesis for the preparation of specialty chemicals, peptides, and conjugates.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for purity and identity. We provide comprehensive analytical data, including HPLC for assay and purity, and IR for structural confirmation. Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture.
