27206-35-5 Usage
Uses
Different sources of media describe the Uses of 27206-35-5 differently. You can refer to the following data:
1. Bis-(Sodium Sulfopropyl)-Disulfide is used as a brightener in copper electroplating,refining the crystal of the copper coating, and improving the current density in copper electroplating baths at a concentration of 10-50mg/L.Bis-(Sodium Sulfopropyl)-Disulfide used as a brightening agent for acid copper baths for decorative and functional deposits. It is functionally compatible with most components of typical copper bath formulation, such as non-ionic surfactants, polymeric amines and other mercapto compounds.Bis-(Sodium Sulfopropyl)-Disulfide for acid copper plating,decorative and functional availability coating (such as: printed circuit board). Bis-(Sodium Sulfopropyl)-Disulfide can be a typical copper formulations,such as non-ionic surfactant,polyamine and other thiol compounds in combination,can also be used in conjunction with the dye, if combined with DPS and EXP2887 with,you will get better results.
2. Brightener and grain refiner for copper plating

Check Digit Verification of cas no
The CAS Registry Mumber 27206-35-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,2,0 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 27206-35:
(7*2)+(6*7)+(5*2)+(4*0)+(3*6)+(2*3)+(1*5)=95
95 % 10 = 5
So 27206-35-5 is a valid CAS Registry Number.
