Description

Benzyl-D7 Paraben CAS NO 1216916-40-3 is a deuterated isotopologue of benzyl paraben, where seven hydrogen atoms are replaced with deuterium, serving as a high-purity internal standard for precise analytical quantification. This compound is critical for ensuring accuracy and reliability in mass spectrometry-based methods, eliminating matrix effects and instrumental variability. It is primarily required by analytical laboratories, pharmaceutical R&D teams, and contract research organizations (CROs) involved in method development, pharmacokinetic studies, and regulatory compliance testing for parabens and related compounds.

Application

• Internal Standard for LC-MS/MS: Essential for the accurate quantification of benzyl paraben and related preservatives in complex biological and environmental matrices.
• Pharmaceutical Research: Used in drug metabolism and pharmacokinetics (DMPK) studies to track the absorption, distribution, metabolism, and excretion of parabens.
• Cosmetic & Personal Care Product Analysis: Enables precise monitoring of benzyl paraben levels to ensure compliance with global safety and concentration regulations.
• Food & Beverage Safety Testing: Supports analytical methods for detecting and quantifying paraben preservatives in food products and packaging.
• Environmental Monitoring: Aids in the trace analysis of parabens as emerging contaminants in water and soil samples.
• Method Development & Validation: Provides a stable, isotopically labeled reference for developing robust, sensitive, and specific analytical protocols.
• Forensic & Clinical Toxicology: Assists in the definitive identification and measurement of parabens in forensic and clinical casework.

Quality Control

Every batch of Benzyl-D7 Paraben is manufactured and analyzed under strict quality management systems to ensure the highest isotopic and chemical purity required for analytical standards. Our products undergo rigorous quality testing, including NMR and mass spectrometry, to confirm deuteration level and chemical identity, ensuring compliance with industry standards for reference materials. Certificates of Analysis (COA) detailing batch-specific purity, isotopic enrichment, and analytical results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere after each use to prevent degradation from moisture absorption.
