Description

3-Aminobenzoic-D4 Acid is a deuterium-labeled analog of 3-aminobenzoic acid, where four hydrogen atoms are replaced by deuterium. This stable isotope-labeled compound is essential for creating internal standards in quantitative mass spectrometry, ensuring unparalleled accuracy and reliability in analytical measurements. It is primarily utilized by research scientists and quality control laboratories in the pharmaceutical, agrochemical, and environmental testing industries.

Application

• Internal Standard for LC-MS/MS: Critical for precise quantification of 3-aminobenzoic acid and related metabolites in pharmacokinetic and bioanalytical studies.
• Pharmaceutical Research: Used in drug metabolism and disposition (DMPK) studies to track the fate of drug compounds and their degradation pathways.
• Environmental Analysis: Serves as a reference standard in the detection and measurement of aminobenzoic acid derivatives in water and soil samples.
• Isotope Dilution Mass Spectrometry (IDMS): Enables highly accurate concentration measurements in complex matrices, a gold-standard technique in analytical chemistry.
• Chemical Synthesis Research: Acts as a deuterated building block for synthesizing more complex labeled compounds for mechanistic studies.

Quality Control

Our 3-Aminobenzoic-D4 Acid is manufactured under strict quality systems to ensure the high isotopic purity and chemical integrity required for analytical applications. Each batch is characterized by advanced spectroscopic and chromatographic techniques, including NMR, HPLC, and MS, to confirm deuterium incorporation and chemical purity. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically ≥98 atom % D), chemical purity (by HPLC), and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) when possible to prevent oxidation and moisture uptake.
