Description

Diethyl-4-Bromobutanephosphonic Acid is a specialized organophosphorus compound featuring a reactive bromobutyl chain. This chemical serves as a versatile building block and key intermediate in advanced organic synthesis, particularly in the formation of carbon-phosphorus bonds. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries who require high-purity intermediates for complex molecular construction.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially those containing phosphonate or phosphate ester functionalities.
• Agrochemical Synthesis: Used in the development of novel herbicides, insecticides, and plant growth regulators that utilize phosphonic acid derivatives.
• Ligand and Catalyst Preparation: Serves as a starting material for synthesizing specialized phosphonate-based ligands used in metal catalysis and coordination chemistry.
• Material Science Research: Employed in the creation of functionalized surfaces, metal-organic frameworks (MOFs), and novel polymers where the phosphonic acid group acts as a robust anchor.
• Chemical Biology Probes: Useful for modifying biomolecules or creating activity-based probes that target enzymes interacting with phosphate esters.
• Flame Retardant Development: Investigated as a potential intermediate for phosphorus-containing flame retardant additives.

Quality Control

Our Diethyl-4-Bromobutanephosphonic Acid is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR (¹H, ³¹P), HPLC, and GC analysis, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from strong bases and incompatible materials. Due to its nature as a strong acid/organic solvent, ensure containers are clearly labeled and stored on secondary containment.
