Description

Eckol is a naturally occurring phlorotannin compound, a type of polyphenol primarily derived from brown seaweed species such as *Ecklonia cava*. This compound is valued for its potent antioxidant, anti-inflammatory, and enzyme-inhibitory biological activities. It serves as a key active ingredient and reference standard for research and development in the pharmaceutical, nutraceutical, and cosmeceutical industries. Professionals in these fields utilize Eckol CAS NO 88798-74-7 for developing therapeutic agents, functional food ingredients, and advanced skincare formulations.

Application

• Pharmaceutical Research & Development: Used as a reference standard and active pharmaceutical ingredient (API) intermediate in studies targeting oxidative stress, inflammation, diabetes, and neurodegenerative diseases.
• Nutraceutical & Functional Food Production: Incorporated into dietary supplements and health foods for its antioxidant properties and potential to support metabolic health.
• Cosmeceutical Formulations: A key active in anti-aging, brightening, and protective skincare products due to its ability to neutralize free radicals and inhibit tyrosinase.
• Biochemical & Life Science Research: Employed in *in vitro* and *in vivo* studies to investigate biological pathways, enzyme kinetics, and cellular mechanisms.
• Analytical Chemistry: Serves as a high-purity certified reference material (CRM) for method development, validation, and quality control in analytical laboratories.

Quality Control

Our Eckol is produced and tested under strict quality management systems to ensure batch-to-batch consistency and high purity for research and industrial use. Each lot undergoes comprehensive analysis including identification, assay, and impurity profiling via advanced chromatographic and spectroscopic techniques. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support compliance with relevant standards for reference materials and can accommodate specific customer requirements for pharmaceutical or nutraceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to minimize exposure to atmospheric humidity. For long-term storage, consider desiccants or inert atmosphere.
