In summary, Dimethyl ether (also known as methyl ethyl ketone) is a solvent and industrial gas. It is also used as a fuel and a paint thinner. Dimethyl ether is not commonly available in stores, and can be expensive to purchase.

Whatever people are willing to pay.
There are many suppliers, have you checked their prices?

well I bought it for $45 for 125grams then they raised the price to around $85 for 125grams, I feel like I'm getting ripped off.

I have had some diffculty finding places to buy chemicals as a person not affiliated with an institution. When I have found outlets that will sell chemicals, they invariably charge more. I have only bought pretty innocuous things: Zn and sodium hydroxide for making "silver/gold" pennies.
I am in the US.
Of course, it wasn't always like this. I had a pretty good chemistry set (Gilbert) when I was a boy, and you can read about Oliver Sacks buying a lump of sodium to throw into a pond when he was a boy in his memoir "Uncle Tungsten." All in all, I am probably happier that my 11 year old son cannot go and buy a lump of sodium from a store to play with.

Yeah, I still have my Gilbert chemistry set, and I think, a fair sampling of the reagents which were shipped with it. Pre-EPA, you could get away with a lot that you can't now. I think if the government could track down all these sets, everyone who had one would be sitting on a hazardous waste site at the least, if not a Superfund site.Quantum Defect said:
Given the off-label uses for some of these chemicals, I can see why suppliers are not eager to sell to individuals, or charge high prices to discourage casual buyers.
The next time you have to undergo a background check to buy OTC cold remedies, thank a Meth head!

"Should?" With or without the liability insurance for supplier, dealer, shipper, packaging, indestructible labelling? Finished product, common sodium salts? Pennies a pound for two nines. Three nines? Times ten. Uncommon anions? Times ten? Hundred bucks a pound.thankz said:

can someone tell me where I can find an isomer of dimethyl ether cheap, I could start a chemical company and resell it for $100 a pound!

Everclear goes for around ten bucks a pound. Not cheap, but half that is taxes.thankz said:

I could even run my car on it 
1. Where do you typically purchase your chemicals from?
I usually purchase my chemicals from reliable suppliers that provide high quality products. Some examples of suppliers I have used in the past include Sigma Aldrich, Fisher Scientific, and VWR.
2. How do you ensure the chemicals you purchase are of good quality?
I always make sure to check the purity and specifications of the chemicals before purchasing. I also read reviews and ask for recommendations from other scientists or colleagues to ensure the reliability of the supplier.
3. Do you have a preferred method of purchasing chemicals?
I prefer to purchase chemicals online as it is convenient and allows for easy comparison of prices and specifications. However, I also occasionally purchase chemicals in person from local suppliers if I need them urgently.
4. Are there any specific precautions you take when purchasing volatile or hazardous chemicals?
Yes, I always make sure to check the safety data sheets for any potential hazards and follow proper safety protocols when handling and storing these chemicals. I also make sure to purchase from reputable suppliers that provide proper labeling and packaging.
5. How do you handle the disposal of chemicals after use?
I follow the proper disposal guidelines and regulations set by my institution or country. This usually involves labeling and storing the waste properly and arranging for safe disposal through a licensed company. I also try to minimize waste by only purchasing the amount of chemicals needed for my experiments.
