General Description
4-DIMETHYLAMINOBENZENEAZO-1-NAPHTHALENE is a chemical compound that is commonly used as a dye in various industries. It is a reddish-orange powder that is insoluble in water but soluble in organic solvents. 4-DIMETHYLAMINOBENZENEAZO-1-NAPHTHALENE is known for its strong coloration properties and is often used in the manufacturing of paints, inks, and textiles. It is also used in the medical field as a histological stain for the detection of proteins and nucleic acids. However, 4-DIMETHYLAMINOBENZENEAZO-1-NAPHTHALENE is a hazardous substance and can cause irritation to the skin, eyes, and respiratory system if not handled properly. Therefore, it is important to observe proper safety precautions when working with this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 607-59-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 607-59:
(5*6)+(4*0)+(3*7)+(2*5)+(1*9)=70
70 % 10 = 0
So 607-59-0 is a valid CAS Registry Number.

Convenient and rapid diazotization and diazo coupling reaction via aryl diazonium nanomagnetic sulfate under solvent-free conditions at room temperature

For the first time, nanomagnetic-supported sulfonic acid is used for conversion of several types of aromatic amine, containing electron-withdrawing groups as well as electron-donating groups to the corresponding azo dyes in excellent yield. The synthesis of these compounds is described by the sequential diazotization-diazo coupling of various aromatic amines with sodium nitrite, nanomagnetic supported sulfonic acid and coupling agents under solvent-free conditions at room temperature. This new method offers several advantages including short reaction time, mild reaction conditions, avoidance of harmful acids, and simple work-up procedure. More importantly, aryldiazonium salts supported on magnetic nanoparticles (aryl diazonium nanomagnetic sulfate) were sufficiently stable to be kept at room temperature in the dry state.
