Description

Dl-Catechin CAS NO 88191-48-4 is a synthetic racemic mixture of the catechin stereoisomers, a prominent member of the flavan-3-ol class of polyphenolic compounds. This versatile chemical intermediate is valued for its antioxidant properties and serves as a key reference standard and building block in research and development. It is essential for manufacturers and researchers in the pharmaceutical, nutraceutical, and cosmetic industries seeking a reliable, high-purity source for product formulation and analytical studies.

Application

• Pharmaceutical Research: Used as a reference standard and active pharmaceutical ingredient (API) intermediate in the development of cardioprotective and neuroprotective agents.
• Nutraceutical Formulation: Incorporated into dietary supplements and functional foods for its potential antioxidant and anti-inflammatory benefits.
• Cosmetic & Personal Care: Serves as a stabilizing and antioxidant agent in anti-aging creams, serums, and sun care products.
• Biochemical Research: Employed in in vitro and in vivo studies to investigate mechanisms of oxidative stress, enzyme inhibition, and cellular signaling pathways.
• Analytical Chemistry: Acts as a critical calibration standard in High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) for the quantification of flavonoids in complex matrices.
• Food Science: Studied for its potential as a natural preservative to enhance the shelf-life and nutritional quality of food products.

Quality Control

Our Dl-Catechin is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its nature of being easily oxidized, prolonged exposure to air should be minimized. For long-term storage, consider under an inert atmosphere.
