CHEMOS search engine

Search the CHEMOS database with more than  180000  chemicals.

The engine searches the database for  CAS No., ChemArt. No,  Chemical name and Common name.

Example:
If you enter the search string: nitro salt acid  hydrate amino di
the search result is:  (2-dimethylamino-4-nitrophenyl) phosphoric acid diammonium salt monohydrate

How  to search / Search instruction

Basicly use for search English language although  the database contains also German, Czech and other phrases.
Use random phrase sequences. 

If you don't know exactly the search string you  can also use 'Search keyword' in the navigation bar at the top.

Search modes

Exact Phrase returns all entries in the database that contain exactly your search term ( if you enter for example Kojic acid the result will be Kojic acid, Kojic acid dipalmitate and Kojic acid sodium salt - if you enter acid Kojic there is no entry with 'acid Kojic' in the database and you receive no result). This mode helps to narrow your search, if there are too many results in the first run.

All entered Words means, that the sequence of the search strings will be ignored. This means 
amin meth sulf = Sulf AMIN Meth and both will give you the result 2-Aminophenol-4-methylsulfone (and many more).

More Examples

2-Aminophenol-4-methylsulfone = amin meth sulf 
N,N'-Dimethylamino-p,p'-triphenyl-o-sulfone = n,n metyl phenyl sulfon 
Dimethyl = di methyl 
Triphenyl methane = tri phenyl methan or methan tri phenyl, there is no   difference in result
There is no diference between N,N and n,n 
Ferric could be Fe(III) 
Please consider,  that Fe(III) is perhaps  Fe (III) and Kojicacid may be Kojic acid ...
