138863-74-8 Usage
General Description
1,2-Naphthoquinone-2-diazido-5-sulfonyl chloride is a compound with the chemical formula C12H5ClN5O4S. It is a diazonium salt derivative of naphthoquinone, commonly used as a photoinitiator in the production of photoresists for printed circuit boards. 1,2-NAPHTHOQUINONE-2-DIAZIDO-5-SULFONYL CHLORIDE is light-sensitive, and when exposed to light, it decomposes to produce highly reactive intermediates that facilitate the crosslinking of polymers. This property makes it useful in applications such as photolithography and photoengraving. Additionally, it has been studied for its potential as a biologically active compound, with some research suggesting anti-tumor and anti-microbial properties. However, due to its reactivity and potentially hazardous nature, it should be handled with care in laboratory settings.
