The yellowing problem of 2-cyanopyridine
Thread Content
Are there any experts who are well-versed in cyanopyridine? In our company, 2-cyanopyridine turns yellow over time. It is presumed that residual ammonia is the cause of this phenomenon, but we are not sure about the mechanism by which ammonia affects the color of cyanopyridine, nor do we know how to effectively prevent this yellowing. We hope that experts can offer some advice
