Application of Pyridyl Hydroxypropane Sulfonate (PPSOH)
Pyridyl Hydroxypropane Sulfonate (PPSOH) is a good nickel plating intermediate which has good leveling power in middle and low current density areas as PPS.
Pyridyl Hydroxypropane Sulfonate (PPSOH) also has an outstanding LCD throwing power, which should be used in combination with BEO, PME, PESS, MOSS,saccharin or auxiliary brighteners.

Electroplating intermediate of Pyridyl Hydroxypropane Sulfonate (PPSOH)
1. pyridyl hydroxypropane sulfonate (PPSOH) is an excellent nickel polishing agent intermediate, high leveling agent for nickel electroplating; It has the same leveling property as PPS, and has good leveling performance in the middle and low regions.
2. PPSOH also has excellent low current density zone displacement capability and needs to be used in conjunction with BEO, PME, PESS or MOSS, saccharin and auxiliary brighteners.
3. the central control index is adopted to control the reaction degree, and the process of removing free pyridine and sulfurous acid is increased at the same time, so that the product contains very little free pyridine, SO32-and organic salt content, thus ensuring the purity and stability of the product.
It prevents abnormal phenomena such as blackening of plated parts, roughness in high areas, blackening in low areas, and more pinholes.
4. in the high current density region, the leveling property is excellent, the decomposition products are few, and the coating can produce a certain white bright effect.
Use of Pyridyl Hydroxypropane Sulfonate (PPSOH)
-Strong leveling agent for preparing electroplating brightener and nickel plating
-watt brightener formula for bright nickel plating, Pyridyl Hydroxypropane Sulfonate (PPSOH) is an efficient bright additive, making the coating good symmetry.
Usually Pyridyl Hydroxypropane Sulfonate (PPSOH) is used with saccharin, acetylene compounds, and wetting agents.
The nickel plating layer thus obtained is bright and flat with good ductility.

Pyridyl Hydroxypropane Sulfonate (PPSOH) is an organosulfur compound with the formula C8H11NO4S.
Using the organic pseudoelement symbol Ms for the methanesulfonyl (or mesyl) group CH3SO2–, it is frequently abbreviated MsCl in reaction schemes or equations.
Pyridyl Hydroxypropane Sulfonate (PPSOH) is a colourless liquid that dissolves in polar organic solvents but is reactive toward water, alcohols, and many amines.
Pyridyl Hydroxypropane Sulfonate (PPSOH) is mainly used to give methanesulfonates by its reaction with alcohols in the presence of a non-nucleophilic base.
In contrast to the formation of toluenesulfonates from alcohols and p-toluenesulfonyl chloride in the presence of pyridine, the formation of methanesulfonates is believed to proceed via a mechanism wherein methanesulfonyl chloride first undergoes an E1cb elimination to generate the highly reactive parent sulfene (CH2=SO2), followed by attack by the alcohol and rapid proton transfer to generate the observed product.
This mechanistic proposal is supported by isotope labeling experiments and the trapping of the transient sulfene as cycloadducts.
