For professionals in the chemical and pharmaceutical sectors, understanding the critical parameters of raw materials is essential for successful product development and research. When it comes to (-)-Epigallocatechin Gallate (EGCG), purity is a paramount concern. As a leading manufacturer and supplier, we recognize the vital role high-purity EGCG plays in various applications, from laboratory studies to the formulation of health products. This article delves into why purity matters and how to ensure you are sourcing quality EGCG (CAS 989-51-5).

The purity of (-)-Epigallocatechin Gallate directly impacts its biological activity and reliability in research settings. Impurities can lead to variable results, potentially compromising scientific conclusions or product efficacy. Therefore, when purchasing EGCG, it is imperative to look for suppliers who clearly state their purity levels, typically confirmed through analytical methods like High-Performance Liquid Chromatography (HPLC). A purity of 97% or higher is generally considered suitable for most research and pharmaceutical applications. As a dedicated manufacturer, we employ rigorous purification techniques to ensure our EGCG meets these exacting standards.

Procurement specialists and researchers should always request a Certificate of Analysis (CoA) with their EGCG order. This document provides critical information about the batch, including its purity, identity confirmation (often via mass spectrometry), and any detected impurities. When you are looking to buy EGCG, partnering with a supplier that transparently shares this data builds trust and ensures you are receiving a product that aligns with your requirements. Furthermore, understanding the physical characteristics, such as its appearance as a white solid, and recommended storage conditions also contributes to maintaining its purity and stability.

As a direct manufacturer of (-)-Epigallocatechin Gallate, we are committed to delivering a product that exceeds expectations. Our manufacturing processes are designed to minimize contaminants and maximize the concentration of active EGCG. We aim to be your go-to supplier for reliable, high-purity EGCG, offering competitive pricing for bulk purchases.
