Description

4-(2,4-Dichlorophenoxy-D3)Butyric Acid is a deuterated analog of the plant growth regulator 2,4-DB, where three hydrogen atoms are replaced by deuterium. This stable isotope-labeled compound is essential for use as an internal standard in mass spectrometry-based analytical methods, providing superior accuracy and reliability for quantitative analysis. It is primarily used by researchers and analytical laboratories in the agrochemical, environmental monitoring, and pharmaceutical industries for method development, residue testing, and metabolic studies.

Application

• Internal Standard for LC-MS/MS and GC-MS: Critical for the precise quantification of 2,4-DB and related phenoxy herbicides in complex matrices.
• Agrochemical Research & Development: Used in metabolism studies, environmental fate analysis, and residue depletion trials to understand the behavior of the parent compound.
• Environmental Monitoring: Enables accurate tracking of herbicide residues in soil, water, and plant samples to assess contamination and compliance with regulatory limits.
• Food Safety Testing: Supports laboratories in monitoring and quantifying pesticide residues on crops and in food products to ensure consumer safety.
• Pharmaceutical Impurity Profiling: Can be employed in trace analysis for related substances in pharmaceutical manufacturing where phenoxy compounds are relevant.
• Method Development & Validation: Serves as a key reagent for developing, optimizing, and validating robust analytical methods in compliance with guidelines like SANCO and FDA.

Quality Control

Every batch of 4-(2,4-Dichlorophenoxy-D3)Butyric Acid is produced and analyzed under strict quality protocols to ensure the high chemical purity and isotopic enrichment required for analytical standards. Our quality assurance includes rigorous testing via NMR, HPLC, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, isotopic purity (D-enrichment), and analytical data is provided with each shipment to support your compliance and research needs.

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); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
