(-)-Epigallocatechin Gallate-d3/d4

(-)-Epigallocatechin gallate (EGCG) is a potent polyphenol found in green tea and is known for its antioxidative and anti-inflammatory properties. As a deuterated derivative, labeled with deuterium atoms, EGCG-d3/d4 is used extensively in research as an internal standard in mass spectrometry-based analyses. EGCG-d3/d4 has the same chemical structure as the non-deuterated EGCG, but with three or four deuterium atoms substituted at specific positions. This labeling allows researchers to distinguish and quantify the labeled compound from other compounds in a sample, especially in complex biological matrices. The chemical information of EGCG-d3/d4 includes its molecular formula, which is C22H14D3O11 or C22H10D4O11, and its molecular weight, which is 472.45 or 468.49 g/mol, respectively. Its melting point is approximately 218-220°C, and it is soluble in water, ethanol, and methanol. EGCG-d3/d4 is used in various applications, including pharmacokinetic studies, metabolic profiling, and biomarker discovery. It is also used in drug discovery and development to assess drug efficacy and toxicity. In addition, EGCG-d3/d4 is used in food and beverage research to study the metabolism and absorption of EGCG in the human body. Overall, EGCG-d3/d4 is a valuable tool in scientific research, providing accurate and precise measurements in various analytical applications.
