Main Uses:

 


Core uses of Tosyl chloride:
1. Organic synthesis field
Sulfonylation reaction:
Reacting with alcohols, phenols, and amines to form sulfonic acid esters (protecting hydroxyl groups) or sulfonamides (protecting amino groups), widely used in the preparation of organic intermediates;
Participate in the epoxidation reaction of 1,2-diol and the conversion of allyl alcohol to allyl chloride.
Selective modification:
Selective control of O - or N-sulfonylation can be achieved by adjusting solvents such as pyridine or triethylamine;
Promote Beckmann rearrangement reaction to generate lactam compounds.
2. Analytical Chemistry Applications
Derivative reagents:
Reacting with hydroxyl/amino compounds to generate easily detectable derivative products for GC-MS, HPLC-MS analysis of drugs, pesticides, and food ingredients;
Detecting drug impurities or preparing stable compounds (such as quality control reagents).
3. Pharmaceutical and Pesticide Industry
Drug synthesis:
Synthesis of sulfonamide drugs (such as metoclopramide), antibiotics, and anticancer drug intermediates;
Pesticide production:
Prepare herbicides (such as metoclopramide) and fungicides (such as metoclopramide).
4. Dyes and Fine Chemicals
Dye intermediates:
Introducing sulfonic acid groups for dispersing dyes, ice dyes, and acid dyes;
Molecular rearrangement reactions involved in hormone synthesis.
5. Polymer materials industry
Aggregation modification:
As an initiator or crosslinking agent for polymerization reactions, used for polymer functionalization modification;
The precursor for synthesizing sulfonated polymer materials.
6. Other industrial applications
Surfactants/Plasticizers: Synthetic industrial surfactants, plasticizers, and lubricants;
Preparation of fine chemicals: used for the synthesis of organic compounds such as ketones, esters, amides, etc.

 

P-Toluene sulfonyl chloride (PTSC) is a white crystalline powder. It has a minimum purity of 99% and a melting point not lower than 67ºC. The maximum water content is 0.05%, and the colority (APHA) should not exceed 20. The maximum content of free acid is 0.3%, and the maximum content of o-toluene sulfonyl chloride (OTSC) is 0.2%.

PTSC is an important organic compound with wide applications in the chemical and industrial fields. It is commonly used in the synthesis of pharmaceuticals, dyes, and high-molecular-weight materials. PTSC exhibits excellent chemical stability and reactivity, making it a valuable raw material for synthesizing intermediates and functional materials.
