Looking for Urea

[wop1969]

I found some ice melter at the local hardware in my search for urea but I cant decyper the contents, can someone help me with this?
I am working on understanding this but it gets confusing when so many are listed at once.

kcl 7447-40-7
nacl 7647-14-5
nh2conh2 57-13-8
c706h14 97-30-3

Here is a pic of the lable of the chems listed above.

You have the wrong number for Urea, it 57-13-6, The jug is correct, you must have read it wrong.

The four ingredients are table salt, potassium salt (sodium free salt, urea, and α-Methyl-(d)-glucoside.

urea is 46-0-0 best to try the garden dept at a lowe's,home depot,menards and look for that number on fertilizer or any place that handles farm chemicals it is a 46% nitrogen based fertilizer. if you still can't find any let me know how many ton(s) you would like....lol

 

[wop1969]

is their a topic that explains the XX-XX-XX numbers and how it works?
I am just starting to figure out how to read the Chem lables let alone the cas thing. But I have no understanding of how it works or what it is.

 

[maltfoudy]

46-0-0 the 1st #is the percent of nitrogen,the second # is the percent of phosphorous,the 3rd # is the percent of potassium

So this numbering systems is just used to to keep track of compounds?

Also is it safe to assume this method is basicly for fertalizer compounds?

These numbers help a farmer determine how much of the 3 major plant nutrients are required for their soil based on a soil test. It is only a vague indicator of the chemical urea. If you see 46-00-00 it only indicates urea because urea as a fertilizer is 46% available nitrogen. If the last numbers aren't zeros other chemicals have been added.

ok so thereticly you might find one that says Urea on the package and say
10-00-00 and it would be urea with 10% nitrogen content?

N-P-K fertilizer nitrogen - phosphate- pottassium
you need Urea 46-0-0 check your local feed store or farmers coop

Don't confuse the two numbering systems.

The NPK system is not the same as the CAS.

NPK is nitrogen phosphorus potassium and is explained here:

CAS registry numbers are used to identify exact compounds and is explained here:

I've already given you a link to look up the CAS numbers above.

Ok so the cas is a cataloging system and NKP is a compound ID system

Dont think it works quite like that...
Since urea is 46%... for it to be 10% it would be another compound with less nitrogen % composition available, afaik
