10421-48-4 Usage
Description
Ferric nitrate, also known as iron(III) nitrate, is a pale violet, green, or grayish-white crystalline solid that can exist in various forms such as lumpy crystals or nonahydrate. It is a strong oxidant and irritant, and it can accelerate the burning of combustible materials, posing a fire hazard when in contact with organic substances. Ferric nitrate is hygroscopic, decomposes at 47°C, and is very soluble in water, alcohol, and acetone.
Uses
Used in Dyeing Industry:
Ferric nitrate is used as a mordant for dyeing buffs and blacks, providing a means to fix dyes onto fabrics and ensuring colorfastness.
Used in Tanning Industry:
In the tanning process, ferric nitrate is utilized to help transform raw hides into leather by tanning agents, which bind to the collagen fibers in the hide.
Used in Analytical Chemistry:
Ferric nitrate is employed in the preparation of analytical standards, which are essential for the calibration and validation of analytical instruments and methods.
Used in Textile Industry:
Ferric nitrate is used for weighting silks, which involves adding weight to the fabric to improve its drape and handle.
Used in Fertilizer and Food Additive Industry:
Ferric nitrate is also used as a component in the production of fertilizers and as an additive in the food industry, although its use in this context may be subject to specific regulations and limitations.
Preparation
Iron(III) nitrate is prepared by the action of nitric acid on iron filings or iron oxide followed by crystallization:
2Fe + 6HNO3 → 2Fe(NO3)3 + 3H2
Fe2O3 + 6HNO3 → 2Fe(NO3)3 + 3H2O
Air & Water Reactions
Soluble in water.
Reactivity Profile
Ferric nitrate is an oxidizing agent. Mixtures with alkyl esters may explode, owing to the formation of alkyl nitrates. Mixtures with phosphorus, tin(II) chloride or other reducing agents may react explosively [Bretherick, 1979 p. 108-109].
Hazard
Dangerous fire risk in contact with organic
materials. Strong oxidant and irritant.
Safety Profile
Mutation data reported.A reactive oxidizer.
Potential Exposure
Ferric nitrate is used in textile dyeing,
tanning, and weighting silk.

agents, oxidizable materials and combustibles including
metal powders, sulfur, and organic materials, combustibles,and easily oxidizable materials. Light sensitive. Aqueous
solution is corrosive to metals.
Check Digit Verification of cas no
The CAS Registry Mumber 10421-48-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,2 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 10421-48:
(7*1)+(6*0)+(5*4)+(4*2)+(3*1)+(2*4)+(1*8)=54
54 % 10 = 4
So 10421-48-4 is a valid CAS Registry Number.
