Cattle brought into West African republic for compound (7)

I believe the answer is:

benzoin

I'm a little stuck... Click here to teach me more about this clue!

'compound' is the definition.
(benzoin is a kind of compound)

'cattle brought into west african republic' is the wordplay.
'cattle' becomes 'zo' (I am not sure about this - if you are sure you should believe this answer much more).
'brought into' means one lot of letters goes inside another.
'west african republic' becomes 'benin' (I've seen this before).
'zo' inserted within 'benin' is 'BENZOIN'.

'for' is the link.

Can you help me to learn more?

I've seen this clue in The Telegraph.
