Chemical Profile

Product Overview

Hydrochloric Acid 37% (HCl) - Technical Grade is a highly concentrated aqueous solution of hydrogen chloride, engineered for demanding industrial applications requiring precise acidity control. Also known as Muriatic Acid or Spirits of Salt, this clear, colorless liquid provides rapid pH adjustment and effective inorganic chemical synthesis. With a concentration of approximately 37% w/w, it serves as a robust reagent for metal finishing, water treatment, and process chemistry.

Manufactured to meet ACS Reagent Grade specifications and USP-NF Monograph standards, this product ensures consistency in density (1.19 g/mL at 25°C) and trace impurity control. It is designed for facilities equipped to handle volatile, corrosive acids, offering reliable performance for titration, acid-base neutralization, and scale removal in controlled industrial environments.

Common Applications

pH Adjustment: Used extensively to lower pH in industrial water treatment and waste stream neutralization to control scaling and verify process parameters.
Metal Surface Treatment: Acts as a powerful pickling agent to remove rust, mill scale, and oxides from steel and other metals before plating or galvanizing.
Chemical Synthesis: Serves as a primary reagent in the production of chlorides, fertilizers, and dyes, as well as in the regeneration of ion exchange resins.
Industrial Cleaning: Effective for cleaning brickwork, concrete, and removing mineral deposits from boiler systems and heat exchangers.
Laboratory Reagent: Utilized for titration, sample digestion, and analytical testing due to its high purity profile.

Safety Precautions

Hydrochloric Acid 37% is a corrosive hazardous material (UN 1789, Class 8). It causes severe skin burns and eye damage and may cause respiratory irritation. Store in a cool, well-ventilated area in corrosion-resistant containers (HDPE or glass), segregated from alkalis, oxidizing agents, and metals. Personnel must wear full chemical-resistant PPE, including neoprene/nitrile gloves, chemical splash goggles, face shields, and acid-resistant clothing. Ensure access to safety showers and eyewash stations. Refer to the Safety Data Sheet (SDS) for comprehensive handling and emergency response procedures.

Benefits

High Purity: Meets ACS and USP-NF standards for critical industrial and analytical applications.
Precise Concentration: Tight assay (36-38%) ensures predictable stoichiometry in chemical reactions.
Versatile Utility: Effective for both heavy industrial cleaning and delicate laboratory synthesis.
Low Impurity Profile: Minimized trace metals protect process integrity and prevent contamination.
