Sulfamic Acid

Sulfamic Acid is an inorganic solid acid with the chemical formula NH₂SO₃H. It typically appears as a white, odorless crystalline powder or granules. Its most notable features are its strong acidity, good water solubility, stability in solid form without being hygroscopic, coupled with the advantages of being non-volatile and relatively less corrosive. It is considered a convenient and safe alternative to sulfuric and hydrochloric acids, widely used in industrial cleaning, water treatment, chemical synthesis, and other fields.

Product Parameters


Product Name (English)Sulfamic Acid
CAS No.5329-14-6
DescriptionA white crystalline solid. Sulfamic acid is a versatile cleaning agent, particularly for removing scale from boilers, heat exchangers, and other industrial equipment. It is also used as a raw material for the production of sweeteners, dyes, and flame retardants.
SpecificationsPurity > 99.5%.
Packaging25 KG/bag.

Basic Properties

  •  Appearance: White orthorhombic crystals or powder

  • Odor: Odorless

  • Density: 2.15 g/cm³

  • Melting Point: Decomposes at ~205°C

  • Solubility: Freely soluble in water, yielding a strongly acidic solution; slightly soluble in methanol; insoluble in ethanol, ether, and other organic solvents

  • Acidity: It is a moderately strong acid (pKa = 1.0) and its salt water solubility is generally good.

  • Stability: Stable at room temperature. Hydrolyzes to ammonium hydrogensulfate in hot water or when heated above its mp

  • Reactivity: Reacts with nitrites to produce nitrogen gas, a reaction commonly used in laboratories and industry to remove nitrites. Reacts with various metal oxides and carbonates to form soluble salts, making it effective in dissolving scale.

Main Applications


  1. Cleaning & Descaling: An efficient and safe cleaning agent widely used to remove calcium carbonate and rust scale from equipment like heat exchangers, boilers, condensers, and cooling towers. It is much less corrosive to metals than hydrochloric acid.

  2. Bleaching & Disinfection: Used as a bleaching agent for textiles, a stabilizer for bleaching paper and pulp. Also used as a chlorine stabilizer and disinfectant in swimming pools.

  3. Chemical Synthesis: Used in the synthesis of sweeteners (e.g., sodium cyclamate), flame retardants, sulfamate salts (e.g., ammonium, sodium, calcium, magnesium), electroplating bath additives, and in the dye and pigment industry.

  4. Other Uses: Used for acidification treatment in the petroleum industry and as a standard acid for analytical titration in laboratories.

Safety Precautions


  1. Corrosivity:

    • The solid and its solutions are corrosive and irritating to the eyes, skin, and respiratory tract. Contact may cause severe burns.

  2. Health Hazards:

    • Inhalation: May cause irritation of the respiratory tract, coughing, and sore throat.

    • Ingestion: Harmful, causes severe irritation and burns to the gastrointestinal tract.

    • Skin Contact: Can cause irritation, pain, and even burns.

    • Eye Contact: Can cause severe irritation, redness, pain, and even permanent eye damage.

  3. Protective Measures:

    • Wear chemical-resistant gloves, protective goggles, and a dust mask when handling.

    • Ensure good ventilation in the workplace and avoid creating dust.

    • Do not mix with strong oxidizing agents (e.g., bleach) or nitrites to prevent violent reactions and the generation of toxic gases (e.g., chlorine, nitrogen oxides).

  4. Storage:

    • Store in a cool, dry, well-ventilated place away from incompatible materials.
