5329-14-6 Usage


As standard in alkalimetry; in acid cleaning; in nitrite removal; in chlorine stabilization for use in swimming pools, cooling towers, paper mills. Solid-acid catalyst in organic synthesis. The acid or its ammonium salt has been recommended for flameproofing fabrics and wood. Metal salts are used in electroplating. Ammonium sulfamate, q.v., is also widely used as a weed killer.


ChEBI: The simplest of the sulfamic acids consisting of a single sulfur atom covalently bound by single bonds to hydroxy and amino groups and by double bonds to two oxygen atoms.


Toxic by ingestion.

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Purification Methods

Crystallise NH2SO3H from water at 70o (300mL per 25g), after filtering, by cooling a little and discarding the first batch of crystals (about 2.5g) before standing in an ice-salt mixture for 20minutes. The crystals are filtered off by suction, washed with a small quantity of ice cold water, then twice with cold EtOH and finally with Et2O. Dry it in air for 1hour, then store it in a desiccator over Mg(ClO4)2 [Butler et al. Ind Eng Chem (Anal Ed) 10 690 1938]. For the preparation of primary standard material see Pure Appl Chem 25 459 1969.

Fire Hazard

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

Reactivity Profile

Sulfamic acid reacts exothermically with bases. Aqueous solutions are acidic and corrosive.


It is used in acidimetric standard.

Air & Water Reactions

Moderately soluble in water [Hawley].

General Description

A white crystalline solid. Density 2.1 g / cm3. Melting point 205°C. Combustible. Irritates skin, eyes, and mucous membranes. Low toxicity. Used to make dyes and other chemicals.

Chemical Properties
