6459-94-5 Usage
Description
ACID RED 114 is an azo dye that is characterized by its bright red color and is available as a powder. It is soluble in water, with a solubility of 60 g/L at 90°C. The dye exhibits good levelness and whiteness, but its color may become slightly dimmed when dyeing with copper and iron ions. ACID RED 114 is primarily used in the diagnostics and textiles industries, but it is also present in wastewater and textile effluents, contributing to environmental hazards. It is listed as an environmental toxin on the US EPA Toxic Release Inventory (TRI) list.
Uses
Used in Diagnostics Industry:
ACID RED 114 is used as a diagnostic agent in various medical applications, such as staining and visualization of biological samples.
Used in Textile Industry:
ACID RED 114 is used as a dye for wool, silk, and their blended fabrics in dyeing and printing processes. It can also be used for leather coloring. This product is particularly used for dyeing wool and roving in a scattered manner.
Standard:
ACID RED 114 meets the following standards in terms of light fastness, soaping, perspiration fastness, oxygen bleaching, and fastness to seawater:
Light Fastness: ISO 3
Soaping: ISO 4
Perspiration Fastness: ISO 5
Oxygen Bleaching: ISO 4-5
Fastness to Seawater: ISO 4-5
Chemical Properties:
ACID RED 114 is a solid azo dye with a bright red color and good solubility in water.
Preparation
3,3′-Dimethylbenzidine double nitriding, respectively with phenol and 7-Hydroxynaphthalene-1,3-disulfonic acid coupling, then use 4-Methylbenzene-1-sulfonyl chloride make phenol hydroxyl esterification.
Reactivity Profile
ACID RED 114 is an azo compound. Toxic gases are formed by mixing compounds containing azo groups with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.

Purification Methods
Salt out three times with sodium acetate, then repeatedly extract it with EtOH and dry the solid in air. [McGrew & Schneider J Am Chem Soc 72 2547 1950, Beilstein 16 II 140.] See Solochrome Violet R in “Aromatic compounds”, Chapter 4.
Check Digit Verification of cas no
The CAS Registry Mumber 6459-94-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,5 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6459-94:
(6*6)+(5*4)+(4*5)+(3*9)+(2*9)+(1*4)=125
125 % 10 = 5
So 6459-94-5 is a valid CAS Registry Number.
