Description

2-Chloro-3-[4-(4-Chlorophenyl)Cyclohexyl-D5]-1,4-Naphthalenedione is a deuterated derivative of a halogenated naphthalenedione, a compound class of significant interest in advanced chemical research and development. This high-purity, isotopically labeled compound is specifically engineered to serve as a critical internal standard or analytical reference material in mass spectrometry and other quantitative analytical techniques. It is essential for researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental testing sectors who require precise, interference-free quantification of its non-deuterated counterpart or related metabolites.

Application

• Analytical Reference Standard: Primary use as a certified internal standard for Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS) to ensure accurate quantification in complex matrices.
• Pharmaceutical Research: Enables precise pharmacokinetic and metabolic studies (ADME) of parent drug compounds, facilitating drug discovery and development processes.
• Environmental Analysis: Used in the detection and quantification of trace-level pollutants, pesticides, or their degradation products in environmental samples (water, soil).
• Agrochemical Development: Supports residue analysis and metabolic pathway studies for novel agrochemicals, ensuring regulatory compliance and safety assessments.
• Forensic Toxicology: Aids in the accurate identification and measurement of specific compounds or toxins in forensic investigations.
• Isotope Dilution Mass Spectrometry (IDMS): Serves as the ideal spike material for this gold-standard quantitative method, guaranteeing high accuracy and precision.

Quality Control

Every batch of our deuterated compounds is synthesized and purified under strict quality-controlled conditions to ensure isotopic purity, chemical purity, and batch-to-batch consistency essential for analytical applications. Identity and purity are confirmed by a suite of advanced analytical techniques including NMR (1H, 13C), High-Resolution Mass Spectrometry (HRMS), and HPLC. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (D-content), chemical purity, and analytical data is provided with each shipment to support your regulatory and research documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). For long-term stability, consider storage under inert atmosphere (argon or nitrogen) in a freezer (-20°C). Keep the container tightly sealed in a dry environment to prevent moisture absorption.
