Urea and Cinnamic acid. Write the important chemical and safety data for lab. Write the structure, compound, melting point, molecular weight, and safety.
Homework Answers
Urea-
Structure-
Melting Point - 
Molecular Weight - 
Safety -
- Urea must always be handled using goggles, dust mask because a long time exposure to urea is injurious to eyes and respiratory tract.
- It should be stored safely and if spilled, the area must be cleaned with water.
- N-labelled urea preparation can be dangerous.
Cinnamic Acid-
Structure-
Melting Point-
Molecular Weight - 
Safety - .
- Cinnamic acid should always be handled with gloves, masks, and goggles as it is irritant to eyes and skin. It also causes irritation if inhaled!

Backgrouund: Material Safety Data Sheets have been prepared for each commercially available chemical compound. There are several sources for MSDS information. In our lab we have hard copies in yellow MSDS binders. We also have the Aldrich Chemical Catalog, the CRC Handbook of Chemistry and Physics, and the Merck Index. Using a search engine, you can also enter the chemical name along with "MSDS." Also, when looking up a particular compound, make sure that you are getting the actual compound...

Bromination of Trans-Cinnamic Acid Lab Question: The melting point of my product is 115-118C. The percent yield was 19.2%. Is the product erythro or threo? From the melting point, I am guessing it is the threo. But wasn't the product supposed to be erythro? Can someone explain this result? And what is a possible reason why the yield is very low?
