Description

Indole-D7 CAS NO 73509-20-3 is a deuterated analog of indole, where seven hydrogen atoms are replaced by deuterium atoms. This isotopic labeling is critical for applications requiring high molecular specificity and minimal background interference, such as in advanced analytical techniques. It is an essential material for researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors who require stable isotope-labeled internal standards or probes for metabolic and pharmacokinetic studies.

Application

• Internal Standard for Quantitative Analysis: Serves as a stable isotope-labeled internal standard in LC-MS and GC-MS for the accurate quantification of indole and related metabolites in complex biological matrices.
• Metabolic Tracing: Used as a deuterium-labeled tracer in drug metabolism and pharmacokinetic (DMPK) studies to investigate metabolic pathways and bioavailability.
• Pharmaceutical Research: Employed in the development and validation of analytical methods for new drug candidates and impurities where indole is a structural component.
• Chemical Synthesis: Acts as a labeled building block for the synthesis of more complex deuterated compounds for research and development.
• Environmental and Food Testing: Utilized in analytical methods to detect and quantify indole derivatives in environmental samples or food products.
