Description
Disperse Orange 76 is an orange azo dye that is commonly used in the dyeing and printing of polyester and blended fabrics. It is characterized by its dark red light orange color and dark orange shade, and is available in the form of an orange powder that is insoluble in water. The dye exhibits good lifting force in polyester and is suitable for dyeing polyester/cotton and polyester/stick blends in a one-bath process.
Uses
Used in Textile Industry:
Disperse Orange 76 is used as a dye for polyester and blended fabrics, providing a dark red light orange color and dark orange shade. It is particularly useful for dyeing polyester/cotton and polyester/stick blends in a one-bath process.
Used in Environmental Testing:
Disperse Orange 76 is also used in environmental testing, specifically for the detection and analysis of dyes and their metabolites in various samples.
Standard:
Disperse Orange 76 meets certain standards for ironing fastness, light fastness, perspiration fastness, and washing fastness, as indicated by the following ratings:
Ironing Fastness: 3-4 (AATCC)
Light Fastness: 6-7 (AATCC)
Perspiration Fastness: 5 (AATCC)
Washing Fastness: 5 (AATCC)
These ratings indicate that Disperse Orange 76 has good resistance to fading and staining under various conditions, making it a reliable choice for dyeing applications.

Check Digit Verification of cas no
The CAS Registry Mumber 13301-61-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,0 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13301-61:
(7*1)+(6*3)+(5*3)+(4*0)+(3*1)+(2*6)+(1*1)=56
56 % 10 = 6
So 13301-61-6 is a valid CAS Registry Number.

Stable diazonium salts of weakly basic amines—Convenient reagents for synthesis of disperse azo dyes
Qiu, Jinjing,Tang, Bingtao,Ju, Benzhi,Xu, Yuanji,Zhang, Shufen
, p. 63 - 69 (2016/08/24)
A new synthetic strategy for industrially important deep-shade disperse azo dyes was presented in this study. The key procedure is to prepare stable solid diazonium salts of weakly basic amines in the absence of concentrated sulfuric acid. Diazotization by tert-butyl nitrite in ethyl acetate was allowed to proceed in the presence of equivalent 1,5-naphthalenedisulfonic acid as stabilizer of diazonium salts and donor of hydrogen ion for the reaction. The separated solid diazonium salts exhibited good thermal stability. The corresponding disperse azo dyes were subsequently synthesized through the azo-coupling of the prepared solid diazonium salts with a range of aromatic tertiary amines. The azo dyes were produced in short reaction time, excellent yields, mild reaction conditions, simple experimental procedure and low energy consumption.
