Description

(2-Carboxyethyl)Triphenylphosphonium Tribromide is a versatile organophosphonium salt and brominating agent, widely recognized for its role in facilitating key organic transformations. Its primary value lies in its ability to act as a stable, crystalline source of bromine for electrophilic bromination and as a precursor for generating reactive ylide intermediates. This compound is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors who require high-purity, reliable reagents for synthesis and scale-up.

Application

• Pharmaceutical Intermediate Synthesis: A key reagent for the bromination of sensitive substrates and the synthesis of complex heterocycles and active pharmaceutical ingredients (APIs).
• Agrochemical Research: Used in the development and production of novel pesticides and herbicides through selective bromination reactions.
• Polymer & Materials Science: Serves as a functional monomer or cross-linking agent precursor for creating specialty polymers with unique properties.
• Organic Synthesis Reagent: Employed as a Wittig reagent precursor for olefination reactions and as a stable bromine source for electrophilic additions and cyclizations.
• Fine Chemical Production: Utilized in the manufacture of dyes, fragrances, and other high-value specialty chemicals requiring precise bromine incorporation.
• Academic & R&D Laboratories: A fundamental tool for methodological development in synthetic organic chemistry and catalysis research.

Quality Control

Our (2-Carboxyethyl)Triphenylphosphonium Tribromide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. Keep away from incompatible materials.
