Tris-(4-anilino-phenyl)-methane, also known as 4,4',4''-tri(4-aminophenyl)methane or TAPM, is an organic compound with the chemical formula C21H18N3. It is a white crystalline solid that is widely used as a chromophore in the synthesis of various fluorescent dyes and indicators, such as fluorescein and its derivatives. TAPM is characterized by its three aniline groups attached to a central methane molecule, which contribute to its unique optical properties. Due to its ability to absorb light in the ultraviolet region and emit fluorescence in the visible spectrum, TAPM and its derivatives have found applications in various fields, including biochemistry, molecular biology, and analytical chemistry, where they are used as markers, probes, and sensors.

4822-48-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4822-48-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,2 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.Calculate Digit Verification of CAS Registry Number 4822-48:
(6*4)+(5*8)+(4*2)+(3*2)+(2*4)+(1*8)=94
94 % 10 = 4
So 4822-48-4 is a valid CAS Registry Number.
