Sodium Salt of M-Nitrobenzene Sulfonic Acid- Ludigol is a mild oxidizing agent that helps to prevent dyes from decomposing (being "reduced" - a chemistry teacher question) during fixation, which causes them to be duller. 
Sodium Salt of M-Nitrobenzene Sulfonic Acid- Ludigol is a very important ingredient when working with deep shades and is considered to be essential by some when working on silk when painting with Fiber Reactive dyes like Procion MX or Vinyl Suphon Liquid Reactive Dyes and then steaming the work.

Sodium Salt of M-Nitrobenzene Sulfonic Acid- Ludigol is also known as resist salt or Matexil PAL. 
Add to Procion MX fibre reactive dyes as a colour enhancer when steam setting for brightest, most vibrant colour results as there is a tendency for procion dyes to go weaker and duller because of the reducing action caused by the heat from steam. 
Adding a small quantity to print paste will help prevent loss of colour. 
Use 30ml per litre of water and 3ml per 100ml in printing paste.

Methods of Manufacturing
In the enamel kettle, first add 350 parts of fuming sulfuric acid, control the temperature of the kettle to 0~5℃, slowly add nitrobenzene under stirring, add 132 parts of nitrobenzene within 1h, and raise the temperature of the kettle to 100℃, keep warm 2h. 
Sampling to measure the end point of sulfonation (drop 1 to 2 drops of material into a 10ml test tube filled with clear water, and no turbidity proves to the end). 
After the sulfonation reaction is completed, it is cooled, slowly added to ice water, and 2,000 parts of common salt are added in about 3 hours. 
After salting out for a few hours, it is allowed to stand overnight, suction filtered, and dried to obtain intermediate m-nitrobenzenesulfonic acid. 
Put m-nitrobenzene sulfonic acid into 500 parts of hot water and boil to dissolve. 
Remove a small amount of sulfone. 
Add 50 parts of soda ash for neutralization, then add activated carbon for decolorization, filter while hot, and cool the filtrate to crystallize. 
After the filter cake is washed with a small amount of water, it is dried below 50°C to obtain the finished product.

Uses:
Sodium Salt of M-Nitrobenzene Sulfonic Acid- Ludigol is used as anti-staining agent for vat dyes, sulfur dyes and color-forming protective agents for dyes, rust remover for ships and nickel remover for electroplating, and is also an intermediate for dyes and vanillin.
Sodium Salt of M-Nitrobenzene Sulfonic Acid- Ludigol is a reagent in the synthesis of azetidinyl ketolides for treatment of susceptible and multidrug resistant community-acquired respiratory tract infections.
Finishing agents
