Description

Hydrogen Chloride is a highly reactive, corrosive gas that is a fundamental chemical building block across numerous industries. Its primary value lies in its strong acidic properties and high volatility, making it an essential reagent for synthesis, pH adjustment, and catalysis. This compound is critical for manufacturers in the chemical, pharmaceutical, and electronics sectors who require a reliable, high-purity source for their processes.

Application

• Chemical Synthesis: A key reagent in the production of vinyl chloride, alkyl chlorides, and other chlorinated organic compounds.
• Pharmaceutical Manufacturing: Used in the synthesis of active pharmaceutical ingredients (APIs) and for pH adjustment during various process stages.
• Electronics & Semiconductor: Employed in the etching and cleaning of silicon wafers and for high-purity chemical vapor deposition (CVD) processes.
• Water Treatment & pH Control: Utilized for regeneration of ion-exchange resins and for precise pH adjustment in industrial wastewater systems.
• Food Processing: Applied as an acidulant (E507) and for the production of hydrolyzed vegetable protein and other food ingredients.
• Laboratory & Analytical Reagent: Serves as a standard acid for titrations and analytical procedures in research and quality control laboratories.
• Metal Processing & Pickling: Used for cleaning and descaling metal surfaces, such as steel, prior to further processing or coating.
• Production of Inorganic Chlorides: A primary raw material for manufacturing metal chlorides like ferric chloride and aluminum chloride.

Quality Control

Our Hydrogen Chloride is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and reliability. We offer various grades, including high-purity electronic and pharmaceutical grades, which are analyzed against rigorous internal specifications. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profiles, and other critical parameters is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from incompatible materials such as strong bases, metals, and oxidizing agents. Due to its highly volatile and corrosive nature, cylinders must be kept upright and secured. Storage temperature should be maintained below 30°C (86°F).
