In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Analytical and synthetic studies on the photodecomposition of nitroimidazole compounds, published in 1987-06-30, which mentions a compound: 4897-25-0, mainly applied to azathioprine photodegradation product identification, Product Details of 4897-25-0.
The photodegradation products and synthetic byproducts of azathioprine (I) were isolated and identified to study their potential role in the photosensitization process. Synthetic byproducts observed in the preparation of I included 1-methyl-5-chloroimidazole, 1-methyl-4-chloroimidazole, and 1-methyl-2,4,5-trichloroimidazole. Photolysis at wavelengths >300 nm for 1 h caused a marked change in the UV spectrum of I, giving increased absorption at longer wavelengths. This may be associated with its reported activity as a photosensitizer.
Compound(4897-25-0)Product Details of 4897-25-0 received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(5-Chloro-1-methyl-4-nitroimidazole), if you are interested, you can check out my other related articles.
