Description

Naphthalene-1,2,3,4,5,6,8-D7, 7-Bromo is a high-purity, deuterium-labeled and brominated derivative of naphthalene, serving as a critical internal standard and analytical tracer in advanced research. This compound is essential for ensuring accuracy and reliability in quantitative mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy, where isotopic purity is paramount. It is primarily utilized by pharmaceutical R&D laboratories, academic research institutions, and analytical service providers specializing in metabolism studies, environmental analysis, and method development.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a deuterated internal standard for the precise quantification of brominated naphthalene analogs and related polycyclic aromatic hydrocarbons (PAHs) in complex matrices.
• Metabolite Tracing in Pharmaceutical Research: Enables the study of drug metabolism and pharmacokinetics (DMPK) for compounds containing brominated aromatic systems.
• NMR Spectroscopy Studies: Provides a non-interfering spectroscopic probe for investigating molecular structure, dynamics, and reaction mechanisms due to its deuterium labeling.
• Environmental Analysis: Acts as a surrogate or tracer in the analysis of brominated flame retardants and other persistent organic pollutants (POPs) in environmental samples.
• Organic Synthesis Intermediate: Serves as a specialized, labeled building block for the synthesis of more complex deuterated and brominated compounds for research purposes.
• Quality Control & Method Development: Critical for developing and validating analytical methods in regulatory and quality control laboratories requiring high specificity and accuracy.

Quality Control

Every batch of Naphthalene-1,2,3,4,5,6,8-D7, 7-Bromo is manufactured and analyzed under strict quality systems to ensure exceptional isotopic and chemical purity for demanding research applications. Our products undergo rigorous quality testing, including NMR (¹H, ¹³C) and mass spectrometry to confirm deuterium incorporation and chemical identity, as well as HPLC for purity assessment. Certificates of Analysis (COA) detailing batch-specific 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 compound is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
