Mood: No Mood

I have used a complex diamine before that was about $10/g and at one point had 4 gallons of it that someone had special ordered, and only used a fraction of, worth about $16,000, as trying to return it for a refund...

Used to fret over chemicals that cost $100 or more, in last few jobs, I have spent $10,000 or more on rare sulfonyl chlorides, chiral amines, sets of DNA starting materials, non-natural amino-acids, and other rare chemicals. But most were project critical for a big project, and that turns out to be a small price compared to other big corporate costs. Worked at IBM 3 decades ago as a coop, and made about $10 million in chips a day. One reagent we used as $300/gallon, and we used about 24 gallons a day in one process, which was done in multiple places a day. I found a way to cut that by 3 gallons a day with no change in the process, and saved about a million per year for them. I got a nice thanks for it... After those things everything seemed cheap.
