What is the Sulfamic acid?

Sulfamic acid is white crystalline solid, while it's Molecular Formula is H3NO3S. white crystalline solid Sulfamic acid is widely used in electroplating, hard-water scale reremovers, acidic cleaning agent, chlorine stabilizers, sulfonating agents, denitrification agents, disinfectants, flame retardants, herbicides, artificial sweeteners and catalysts.Sulfamic acid is a precursor to sweet-tasting compounds. Reaction with cyclohexylamine followed by addition of NaOH gives C6H11NHSO3Na, sodium cyclamate.Sulfamic acid is a water-soluble, moderately strong acid. An intermediate between sulfuric acid and sulfamide, it can be used as a precursor to sweet-tasting compounds, a therapeutic drug component, an acidic cleaning agent, and a catalyst for esterification.

What is the CAS number for Sulfamic acid?

The CAS number of Sulfamic acid is 5329-14-6.

What is Sulfamic acid (5329-14-6) used for?

Sulfamic acid, also known as the monoamide of sulfuric acid, is a strong inorganic acid that appears as a white crystalline solid with a density of 2.1 g/cm3 and a melting point of 205°C. It is combustible, has low toxicity, and can irritate skin, eyes, and mucous membranes. Sulfamic acid is soluble in water and liquid ammonia, slightly soluble in methanol, and insoluble in ethanol, ether, carbon disulfide, and liquid sulfur dioxide. It is an intermediate between sulfuric acid and sulfamide, and can be used as a precursor to sweet-tasting compounds, a therapeutic drug component, an acidic cleaning agent, and a catalyst for esterification.InChI:InChI=1/H3NO3S/c1-5(2,3)4/h(H3,1,2,3,4)

Sulfamic acid(Cas 5329-14-6) Usage

Reactions	Sulfamic acid is a strong acid that reacts with many basic compounds. It is heated to above the melting point (209°C) under normal pressure to begin to decompose, and continues to be heated to above 260°C to decompose into sulfur trioxide, sulfur dioxide, nitrogen, hydrogen and water.(1) Sulfamic acid can react with metals to form transparent crystalline salts. Such as:2H2NSO3H+Zn→Zn(SO3NH2)2+H2.(2) Can react with metal oxides, carbonates and hydroxides:FeO+2HSO3NH2→Fe(SO3NH2)2+H2O2CaCO3+2HSO3NH2→Ca(SO3NH2)2+H2O+CO23Ni(OH)2+2HSO3NH2→Ni(SO3NH2)2+H2O.(3) Can react with nitrate or nitrite:HNO3+HSO3NH2→H2SO4+N2O+H2O2HNO2+HSO3NH2→H2SO4+N2+H2O.(4) Can react with oxidants (such as potassium chlorate, hypochlorous acid, etc.): KClO3+2HSO3NH2→2H2SO4+KCl+N2+H2O22HOCl+HSO3NH2→HSO3NCl2+2H2O
Air & Water Reactions	Moderately soluble in water [Hawley].
Reactivity Profile	Sulfamic acid reacts exothermically with bases. Aqueous solutions are acidic and corrosive.
Hazard	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.
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.
Flammability and Explosibility	Nonflammable
Safety Profile	Poison by intraperitoneal route. Moderately toxic by ingestion. A human skin irritant. A corrosive irritant to skin, eyes, and mucous membranes. A substance that migrates to food from packaging materials. Violent or explosive reactions with chlorine, metal nitrates + heat, metal nitrites + heat, fuming HNO3. When heated to decomposition it emits very toxic fumes of SOx and NOx. See also SULFONATES.
Potential Exposure	Sulfamic acid is used in metal and ceramic cleaning, bleaching paper pulp; and textiles metal; in acid cleaning; as a stabilizing agent for chlorine and hypochlorite in swimming pools; cooling towers; and paper mills.
Shipping	UN2967 Sulfamic acid, Hazard class: 8; Labels: 8-Corrosive material.
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.
Incompatibilities	The aqueous solution is a strong acid. Reacts violently with strong acids (especially fuming nitric acid), bases, chlorine. Reacts slowly with water, forming ammonium bisulfate. Incompatible with ammonia, amines, isocyanates, alkylene oxides; epichlorohydrin, oxidizers.
Application	Sulfamic acid, the monoamide of sulfuric acid, is a strong inorganic acid. It is generally used in chemical cleaning processes like removal of nitrites, carbonate- and phosphate-containing deposits.Sulfamic acid can be used as a catalyst in:Friedlander quinoline synthesis.Liquid Beckmann rearrangement for the synthesis of amides from ketoximes.The preparation of α-aminophosphonates via a three-component reaction between aldehydes, amines, and diethyl phosphite.
Definition	ChEBI: Sulfamic acid is 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. It is a strong acid, readily forming sulphamate salts, which is extremely soluble in water and normally exists as the zwitterion H3N+. SO3–.
General Description	Sulfamic acid appears as 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. It is used as a raw material for the preparation of a synthetic sweetener i.e, sodium cyclohexylsulfamate.
