Description

Aminopropyl Dihydrogen Phosphate is an organophosphorus compound featuring both an amino and a phosphate functional group. This unique bifunctional structure makes it a valuable intermediate for synthesizing specialized surfactants, corrosion inhibitors, and surface-modifying agents. It is particularly sought after by manufacturers in the agrochemical, pharmaceutical, and specialty chemical industries for creating performance chemicals with tailored properties.

Application

• Surfactant & Detergent Intermediate: Used in the synthesis of amphoteric and cationic surfactants for personal care and industrial cleaning formulations.
• Corrosion Inhibition: Serves as a key component in formulating corrosion inhibitors for metal treatment and cooling water systems.
• Surface Modification Agent: Employed to functionalize surfaces of materials like silica, glass, or metals to improve adhesion and compatibility.
• Pharmaceutical Intermediate: Utilized in the synthesis of prodrugs and active pharmaceutical ingredients (APIs) that require phosphate ester linkages.
• Agrochemical Synthesis: Acts as a building block for certain herbicides, plant growth regulators, and pesticide formulations.
• Flame Retardant Synergist: Incorporated into polymer systems to enhance flame-retardant properties.
• Chelating Agent Precursor: Used to produce chelating agents for water treatment and metal ion sequestration.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to decomposition or caking.
