Uses
Used in Textile Industry:
Trisodium 5-[[4'-[[8-[(2,4-diaminophenyl)azo]-1-hydroxy-3,6-disulphonato-2-naphthyl]azo]-3,3'-dimethyl[1,1'-biphenyl]-4-yl]azo]salicylate is used as a dye for textiles due to its color-changing properties and solubility in water. Its ability to produce different shades under various conditions makes it suitable for creating unique and vibrant colors in fabrics.
Used in Analytical Chemistry:
trisodium 5-[[4'-[[8-[(2,4-diaminophenyl)azo]-1-hydroxy-3,6-disulphonato-2-naphthyl]azo]-3,3'-dimethyl[1,1'-biphenyl]-4-yl]azo]salicylate can be used as an analytical reagent in various chemical tests, particularly those involving the detection and measurement of metal ions or other chemical species. Its color-changing properties in response to different chemical environments make it a valuable tool for qualitative and quantitative analysis.
Used in Dye Synthesis:
Trisodium 5-[[4'-[[8-[(2,4-diaminophenyl)azo]-1-hydroxy-3,6-disulphonato-2-naphthyl]azo]-3,3'-dimethyl[1,1'-biphenyl]-4-yl]azo]salicylate can be used as an intermediate in the synthesis of other dyes and pigments. Its unique structure and reactivity make it a potential building block for the development of new dyes with improved properties.
Standard:
trisodium 5-[[4'-[[8-[(2,4-diaminophenyl)azo]-1-hydroxy-3,6-disulphonato-2-naphthyl]azo]-3,3'-dimethyl[1,1'-biphenyl]-4-yl]azo]salicylate exhibits the following properties according to the provided standard:
Acid Resistance: 3-4
Alkali Resistance: 3-4
Light Fastness: 2
Soaping: 2
Water: 3
Fading: 2-3
Stain: 2-3
Fading: 1-2
ISO: 3-4
AATCC: 2-3
These properties indicate that the compound has moderate resistance to acids and alkalis, fair light fastness, and good performance in soaping and water resistance. However, it has lower ratings in terms of fading and staining, suggesting that it may not be suitable for applications requiring high color stability.
Preparation
3,3′-Dimethylbenzidine double nitriding,first coupled with 2-Hydroxybenzoic acid, and then in alkaline conditions and 4-Amino-5-hydroxynaphthalene-2,7-disulfonic acid?coupling, its product to diazo, and Benzene-1,3-diamine coupling.

Check Digit Verification of cas no
The CAS Registry Mumber 6505-12-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,0 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6505-12:
(6*6)+(5*5)+(4*0)+(3*5)+(2*1)+(1*2)=80
80 % 10 = 0
So 6505-12-0 is a valid CAS Registry Number.
