Description

2-(Chloroethyl) Phosphonic Acid-D4 is a deuterated analog of the plant growth regulator ethephon, serving as a critical internal standard and tracer in analytical chemistry. This high-purity isotopically labeled compound is essential for ensuring accurate quantification and metabolic pathway elucidation in complex matrices. It is primarily required by agrochemical research laboratories, environmental testing facilities, and pharmaceutical development teams for advanced mass spectrometry and NMR studies.

Application

• Internal Standard for LC-MS/MS & GC-MS: Provides precise quantification of ethephon and related metabolites in residue analysis for food safety and environmental monitoring.
• Metabolic Pathway Tracing: Used in plant physiology and biochemistry research to study the uptake, translocation, and degradation of ethephon using deuterium labeling.
• Method Development & Validation: Critical for developing and validating robust analytical methods in compliance with regulatory guidelines (e.g., EPA, EU).
• Pharmaceutical Impurity Profiling: Aids in the identification and quantification of process-related impurities or degradation products in synthetic pathways.
• Stable Isotope Dilution Assays (SIDA): Enables highly accurate and reproducible results in quantitative analysis, minimizing matrix effects.
• Quality Control Reference Material: Serves as a certified reference material for calibrating instruments and verifying analytical results in quality control laboratories.

Quality Control

Every batch of 2-(Chloroethyl) Phosphonic Acid-D4 is manufactured and analyzed under strict quality management systems. We guarantee high chemical and isotopic purity verified by advanced spectroscopic and chromatographic techniques, including NMR, HPLC, and Mass Spectrometry. A comprehensive Certificate of Analysis (COA) detailing batch-specific results for identity, assay, isotopic enrichment, and purity is provided with each shipment to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a desiccated environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
