Description

Secoisolariciresinol is a naturally occurring lignan phytoestrogen found in high concentrations in flaxseed. This compound is valued for its significant biological activity and role as a key metabolic precursor. It serves as a critical raw material and reference standard for the pharmaceutical, nutraceutical, and research sectors. Industries utilize it for developing health supplements, functional foods, and in clinical research focused on hormonal balance and chronic disease prevention.

Application

• Pharmaceutical Intermediate: Used in the synthesis of more complex pharmaceutical agents and hormone-related therapies.
• Nutraceutical & Dietary Supplements: A key active ingredient in formulations targeting cardiovascular health, menopausal symptoms, and antioxidant support.
• Reference Standard: Essential for analytical method development, quality control, and quantification in pharmaceutical and food testing laboratories.
• Functional Food & Beverage Fortification: Incorporated into food products like breads, cereals, and beverages to enhance their nutritional profile.
• Cosmeceutical Research: Investigated for its potential anti-aging and skin-protective properties in topical formulations.
• Academic & Clinical Research: Employed in studies exploring the chemopreventive, anti-inflammatory, and metabolic effects of lignans.

Quality Control

Our Secoisolariciresinol is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure high purity and consistency, meeting the stringent requirements for research and production use. We provide comprehensive Certificates of Analysis (COA) detailing identity, purity, and impurity profiles, typically determined by HPLC, NMR, and MS. Specifications can be tailored to meet research-grade, nutraceutical-grade, or pharmaceutical reference standard requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. This product is easily oxidized (store under inert atmosphere) and light-sensitive (store away from light). Keep the container sealed under an inert gas such as argon or nitrogen to prevent degradation.
