Description

D,L-Sulforaphane L-Cysteine is a synthetic, stabilized derivative of the potent natural isothiocyanate sulforaphane, designed to enhance bioavailability and handling stability. This compound is crucial for research and development in nutraceutical and pharmaceutical applications due to its role as a precursor to the active sulforaphane, a well-studied activator of the Nrf2 pathway. It is primarily sought by manufacturers in the dietary supplement, functional food, and advanced life science research sectors for formulating products targeting cellular health and antioxidant defense.

Application

• As a key active ingredient or precursor in high-potency dietary supplements and nutraceuticals.
• For formulation into functional foods and beverages designed to support antioxidant and detoxification pathways.
• As a critical reference standard and intermediate in pharmaceutical research for drug discovery related to cytoprotection.
• In advanced life science research to study the Nrf2-Keap1 signaling pathway and its implications in oxidative stress.
• For the development of specialized cosmeceutical products aimed at skin health and protection against environmental stressors.
• As a stabilized raw material for clinical trial supplies where consistent quality and bioavailability are paramount.

Quality Control

Our D,L-Sulforaphane L-Cysteine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for research and nutraceutical use. Certificates of Analysis (COA) detailing all test results are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as indicated on the label. This material is easily oxidized; for long-term storage, consider under an inert atmosphere. Keep container tightly sealed in a dry environment to minimize moisture uptake.
