The present invention relates to novel pyrimidine derivatives and their use in perfume compositions. The novel pyrimidine derivatives of the present invention are represented by the following formula:
wherein m and n are integers that when m is 0, n is 1; when m is 1, n is 0 or 1; or when m is 2, n is 0;
wherein (CH)
m
and (CH)
n
are each independently optionally substituted with a substituent selected from the group consisting of methyl and ethyl;
wherein X is selected from the group consisting of N, O, and S; and
wherein R
1
and R
2
each independently represent H or a hydrocarbon group, or R
1
and R
2
together represent a fused ring or a ring system,
with the proviso that when R
1
is H, R
2
is not H.
