4,4'-(2-chlorobenzylidene)di-2,5-xylidine, also known as C.I. Basic Yellow 2, is an organic compound with the chemical formula C24H21ClN2. It is a synthetic dye that belongs to the class of azo dyes, characterized by the presence of an azo group (-N=N-). 4,4'-(2-chlorobenzylidene)di-2,5-xylidine is used as a colorant in various applications, including textiles, plastics, and printing inks. It is known for its bright yellow hue and good lightfastness. The molecule consists of two xylidine groups connected by a 2-chlorobenzylidene bridge, which contributes to its chemical stability and color properties. Due to its chemical structure, it is also referred to as 2-chloro-4,4'-azobenzene-2',4''-diamine or 2-chloro-4,4'-(2,5-xylylidene)diphenylamine. It is important to note that, like many azo dyes, it may have environmental and health concerns associated with its use, and regulations may dictate its application and disposal.
The CAS Registry Mumber 81-71-0 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 81-71: (4*8)+(3*1)+(2*7)+(1*1)=50 50 % 10 = 0 So 81-71-0 is a valid CAS Registry Number.
