Description

Pentyl Dihydrogen Phosphate is an organophosphorus compound that serves as a versatile intermediate and reagent in synthetic chemistry. Its value lies in its bifunctional nature, combining a hydrophobic pentyl chain with a strongly acidic phosphate group, making it useful for modifying surface properties and acting as a catalyst or ligand precursor. This chemical is primarily needed by researchers and manufacturers in the pharmaceutical, agrochemical, and specialty materials sectors for developing new active ingredients and functional additives.

Application

• As an acid catalyst or ligand precursor in organic synthesis and metal complexation reactions.
• As a surface modification agent or corrosion inhibitor in metal treatment and coating formulations.
• As an extractant or ionophore in analytical chemistry for metal ion separation and sensing applications.
• As a key chemical intermediate in the synthesis of more complex phosphate esters, nucleotides, or phospholipid analogs.
• In lubricant additives and flame retardant research due to its phosphorus content.
• For buffer preparation in specialized biochemical and diagnostic applications requiring specific pH control.

Quality Control

Our Pentyl Dihydrogen Phosphate is produced under a rigorous quality management system. Each batch undergoes comprehensive analytical testing, including assay by titration and identification by FT-IR and NMR spectroscopy, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality parameters. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its nature as a strong acid/organic solvent, keep away from heat, sparks, and incompatible materials such as strong bases and oxidizing agents. The container must be kept tightly sealed to prevent moisture absorption and potential decomposition.
