Description

Cycloalliin Hydrochloride Monohydrate Standard is a high-purity reference material essential for analytical and research applications. This compound serves as a critical standard for the accurate quantification and identification of cycloalliin, a key bioactive sulfur-containing amino acid derivative found in *Allium* species like garlic and onions. It is primarily required by analytical laboratories, research institutions, and quality control departments within the nutraceutical, pharmaceutical, and food science industries. The product is supplied with a fully characterized Certificate of Analysis to ensure reliability and traceability in your work.

Application

• Analytical Reference Standard: Primary use as a high-purity standard for HPLC, LC-MS, and GC-MS methods in quantitative analysis.
• Phytochemical Research: Used in studies investigating the biosynthesis, metabolism, and health benefits of organosulfur compounds in plants.
• Nutraceutical & Functional Food QC: Essential for standardizing and authenticating garlic, onion, and other *Allium*-based extracts and supplements.
• Method Development & Validation: Critical for developing, calibrating, and validating new analytical protocols in food and pharmaceutical laboratories.
• Biochemical Studies: Employed as a substrate or reference in enzymatic and metabolic pathway research related to sulfur amino acids.
• Pharmacological Research: Used as a standard in studies exploring the potential cardiovascular and antioxidant properties of cycloalliin.
