Description

n-(3-Chloro-2-Hydroxypropyl)Dimethylamine, Hydrochloride Salt is a versatile organic intermediate with a reactive chlorohydrin and tertiary amine structure. This compound matters for its role as a key building block in the synthesis of specialty chemicals and polymers, offering a pathway to introduce cationic functionality. It is primarily needed by manufacturers in the water treatment, personal care, and textile industries for producing quaternary ammonium compounds and other functional additives.

Application

• Synthesis of Cationic Monomers and Polymers: A crucial precursor for manufacturing polyelectrolytes, flocculants, and ion-exchange resins used in water purification and papermaking.
• Production of Biocides and Sanitizers: Used to create quaternary ammonium compounds (Quats) for disinfectants, algicides, and industrial preservatives.
• Textile and Leather Auxiliaries: Serves as an intermediate for softeners, leveling agents, and antistatic agents applied to fibers and hides.
• Personal Care Ingredients: Employed in the synthesis of conditioning agents and emulsifiers for hair care and cosmetic formulations.
• Epoxy Resin Modifiers: Acts as a curing agent or reactive diluent to modify the properties of epoxy systems for coatings and adhesives.
• Pharmaceutical Intermediates: Utilized in the research and development of active pharmaceutical ingredients (APIs) and drug delivery systems.

Quality Control

Our n-(3-Chloro-2-Hydroxypropyl)Dimethylamine, Hydrochloride Salt is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with each shipment to support your quality assurance protocols.

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). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and handling properties.
