propylene carbonate toxicity?

i seem to not find much information on this chemical for one the most important why is it considered hazardous and what precautions need to be taken when handling this solvent.

the fire diamond only shows 1 heath, but it needs hazmat fee in transport i don't understand?

I don't believe propylene carbonate is significantly more hazardous than other similar organic solvents (thf, acetone, ethyl acetate, etc.). That being said, it doesn't mean that it's not hazardous, if a large amount were to be spilled during shipment it could potentially pose some hazards; however for routine lab use it's not really hazardous. Just don't drink it!

NOTE: don't use sciencelab.com, they are a scam website and will steal your money!

I think it would be much less toxic than dimethyl carbonate, the alkylating agent, which is actually considered to be low toxicity. Instead of the reactive methyl group you have propylene in a stable ring configuration

Just because you pay hazmat does not mean it is toxic. Ether, ethanol, ethyl acetate and acetone are all of very low toxicity but they still require hazmat charges, due to flammability. With more common chemicals which are not extremely hazardous, small quantities may be shipped ORM-D as consumer commodities, but this does not mean they are not hazardous materials (hazmat charges are simply waived).

thank you i was more using the site for reference
very informative would the process
also seems cheaper just to make it unfortunately this is all i can find on the process reaction of urea and propylene glycol over zinc-iron double oxide catalyst
also not sure what is meant buy zinc-iron double oxide catalysis oxidized galvanized iron

When the analogue guy has a question like this — he
pulls from one of his shelves - Sax's Dangerous Properties of
Industrial Materials. I dobe owning the 9th 1996 edition.
You can buy the current edition w/ CD from Amazon.com for US $1150.

This from TOXNET

Don't know why its Hazmat find not I it on el

Too much water in your lungs is dangerous also ,
so beware dangerous cosmetic skin products !

For easy production of elemental alkali metals , Proplyene Carbonate
dissolves those chlorides which can then be electrodeposited at the cathode.
