How pure is this chloroform?

hopefully this question is in the right place.


I'm a biologist not a chemist (so sorry if this is a stupid question!)- I'm doing some RNA extractions from brain tissue which requires the use of Chloroform. In the manual, it specifies:


Chloroform must not contain isoamyl alcohol or other additives and must be pure.


This is what it says on the label:

Does this count as 'pure'? Obviously pure is quite a subjective term, but it doesn't to my eye contain any isoamyl alcohol, so I suspect it should be OK - but I thought it best to check.
