Description

1-Stearoyl-3-Chloropropanediol is a synthetic fatty acid derivative, specifically a chlorinated diol ester of stearic acid. This compound serves as a versatile chemical intermediate and functional additive, valued for its ability to introduce both lipophilic and reactive chlorohydrin moieties into molecular structures. It is primarily utilized by manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for synthesis and formulation processes.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring lipophilic side chains for enhanced bioavailability.
• Agrochemical Synthesis: Serves as a key building block for creating herbicides, fungicides, and plant growth regulators with tailored properties.
• Polymer Modification: Acts as a reactive monomer or cross-linking agent in the production of specialty polymers, polyesters, and epoxy resins to modify flexibility and hydrophobicity.
• Surfactant & Emulsifier Precursor: Utilized in the manufacture of non-ionic surfactants and emulsifiers for industrial and cosmetic formulations.
• Lubricant Additive: Functions as a precursor for high-performance ester-based lubricant additives that improve thermal stability and reduce friction.
• Research & Development: Employed in organic chemistry R&D for studying esterification reactions and chlorohydrin chemistry.

Quality Control

Our 1-Stearoyl-3-Chloropropanediol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profile, and identity confirmation, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting purity, physical characteristics, and test results are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
