hahahaha , the product obtained after brominating of MPF:))

okay alright, How many parts of sodium thiosulfate are diluted into how many parts of water for use in flushing brometone? ( gr+ml = 100ml sodium thiosulfate )

Hello , No it's just a question from noob person as a expert can you share some information about this question topic ? :)

Hello everyone, I need to prepare a 100ml solution of sodium thiosulfate. I have sodium thiosulfate in solid form, and I'm not sure about the correct procedure for dilution. Can anyone please guide me through the steps to accurately dilute sodium thiosulfate to achieve this 100ml solution?

I bought from not official vendor and no one asked something.

Thank you for your insight. I appreciate it. Now, I'm curious about something else. Does the quality of 4′-Methylpropiophenone from Germany and China significantly impact the final result?

A few days ago, I purchased 100ml of 4′-Methylpropiophenone for approximately $100. However, today, I learned from a friend that the price for 1 liter of 4′-Methylpropiophenone in Russia is around $210. I'm curious to know from experts why there is such a significant price difference.
