Description

Benzoic Acid-D5 CAS NO 1079-02-3 is a stable isotope-labeled analog of benzoic acid, where five hydrogen atoms are replaced with deuterium. This high-purity standard is critical for ensuring accuracy and reliability in quantitative analytical methods. It is an essential material for researchers and quality control laboratories in the pharmaceutical, food and beverage, and environmental testing industries who require precise internal standards for mass spectrometry and NMR spectroscopy.

Application

• Used as an internal standard in Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS) for the accurate quantification of benzoic acid and related compounds.
• Essential in metabolic pathway studies and pharmacokinetic research within pharmaceutical development to track drug metabolism.
• Employed in food safety and quality control laboratories for the precise analysis of benzoic acid, a common preservative.
• Serves as a deuterated NMR solvent shift reference or as a starting material for synthesizing other deuterium-labeled compounds.
• Applied in environmental analysis to detect and measure benzoic acid and its derivatives in complex matrices.
• Utilized in academic and industrial research for mechanistic studies and method development requiring isotopic labeling.

Quality Control

Our Benzoic Acid-D5 is manufactured under strict quality systems to ensure high isotopic and chemical purity, meeting the exacting requirements of analytical reference standards. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing specifications for isotopic enrichment (atom % D), chemical purity (by HPLC), and identity confirmation (by NMR and IR). We adhere to relevant ISO guidelines and can provide material tailored for use under GMP environments upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at a controlled room temperature (15-25°C) in a dry, well-ventilated area. Keep the container sealed to prevent moisture absorption and potential contamination.
