12226-33-4 Usage
Preparation
2-Amino-5-(2-bromoacrylamido)benzenesulfonic acid?diazo, and?4-Hydroxy-6-(methylamino)naphthalene-2-sulfonic acid in acid conditions coupled.
Properties and Applications
blu-ray red. Red purple powder. 90 ℃ water solubility in for 100 g/L. Suitable for dyeing in weak acid dye bath, pH control in 5 ~ 6 between, general join 1% of leveler PW-BX, dye bath temperature rise to 70 ~ 75 ℃ to heat preservation 15 to 16 minutes, depending on the dyeing depth and decide. Such as dyeing depth greater than 1%, need to use liquid ammonia in post-processing, pH value for 8. 5, 15 minutes time, temperature of 80 ℃. The dye levelness is bad, but good color fastness, dyeing fabrics after bright color. Usean hot mama taught wear take a save smaller MM also can be used for silk, wool fabric printing.

Check Digit Verification of cas no
The CAS Registry Mumber 12226-33-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,2 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 12226-33:
(7*1)+(6*2)+(5*2)+(4*2)+(3*6)+(2*3)+(1*3)=64
64 % 10 = 4
So 12226-33-4 is a valid CAS Registry Number.
