Description

Cyclohexanecarboxylic-D11 Acid is a stable isotope-labeled analog of cyclohexanecarboxylic acid, where eleven hydrogen atoms are replaced by deuterium. This high isotopic purity is critical for applications requiring precise internal standards and non-interfering tracers in advanced analytical techniques. It is an essential material for researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors who require reliable deuterated building blocks for metabolic studies, quantitative analysis, and mechanistic research.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative internal standard in LC-MS and GC-MS analysis for accurate measurement of cyclohexanecarboxylic acid and related compounds in complex biological and environmental matrices.
• Metabolic Pathway Tracing: Serves as a deuterium-labeled tracer in pharmaceutical and biochemical research to study drug metabolism, degradation pathways, and bioavailability.
• NMR Spectroscopy Solvent & Reagent: Employed as a shift reagent or in deuterated solvent systems for Nuclear Magnetic Resonance (NMR) spectroscopy to elucidate molecular structures without signal interference from protons.
• Synthesis of Deuterated Compounds: Acts as a key synthetic intermediate for preparing more complex deuterium-labeled fine chemicals, active pharmaceutical ingredients (APIs), and specialty materials.
• Environmental Analysis: Facilitates the detection and quantification of carboxylic acid pollutants and their metabolites in environmental monitoring programs.
