Abstract: The invention relates to a compound of general formula (I) wherein: A) a) R<sub>4</sub>, R<sub>5</sub>, and R<sub>7</sub> each represent a hydrogen atom and R<sub>3</sub>, R<sub>6</sub> and R<sub>8</sub> each represent a methyl radical, or b) R<sub>4</sub>, R<sub>6</sub>, and R<sub>7</sub> each represent a hydrogen atom and R<sub>3</sub>, R<sub>5</sub> and R<sub>8</sub> each represent a methyl radical, or c) R<sub>3</sub>, R<sub>6</sub> and R<sub>7</sub> each represent a hydrogen atom and R<sub>4</sub>, R<sub>5</sub> and R<sub>8</sub> each represent a methyl radical, and the dotted lines are present and represent cis-double bonds or trans-double bonds, and R<sub>1</sub> represents a hydrogen atom and R<sub>2</sub> represents an OH, OCH<sub>3</sub> or OC<sub>2</sub>H<sub>5</sub> group, or the dotted lines are absent and R<sub>1</sub> represents a hydrogen atom and R<sub>2</sub> represents an OCH<sub>3</sub> group or an OC<sub>2</sub>H<sub>5</sub> group; or B) R<sub>1</sub>, R<sub>4</sub>, and R<sub>6</sub>each represent a hydrogen atom and R<sub>2</sub>, R<sub>3</sub> and R<sub>5</sub> each represent a methyl radical, and the dotted lines are present and represent cis-double bonds or trans-double bonds, and R<sub>7</sub> represents a hydrogen atom and R<sub>8</sub> represents an OH, OCH<sub>3</sub> or OC<sub>2</sub>H<sub>5</sub> bond, or the dotted lines are absent and R<sub>7</sub> represents a hydrogen atom and R<sub>8</sub> represents an OCH<sub>3</sub> group or an OC<sub>2</sub>H<sub>5</sub> group. The inventive compound is an alcoholic derivative or an ether derivative. The invention also relates to the use of at least one compound of formula (I) as an odorant agent. The invention relates to a compound of general formula (I) wherein: A) a) R<sub>4</sub>, R<sub>5</sub>, and R<sub>7</sub> each represent a hydrogen atom and R<sub>3</sub>, R<sub>6</sub> and R<sub>8</sub> each represent a methyl radical, or b) R<sub>4</sub>, R<sub>6</sub>, and R<sub>7</sub> each represent a hydrogen atom and R<sub>3</sub>, R<sub>5</sub> and R<sub>8</sub> each represent a methyl radical, or c) R<sub>3</sub>, R<sub>6</sub> and R<sub>7</sub> each represent a hydrogen atom and R<sub>4</sub>, R<sub>5</sub> and R<sub>8</sub> each represent a methyl radical, and the dotted lines are present and represent cis-double bonds or trans-double bonds, and R<sub>1</sub> represents a hydrogen atom and R<sub>2</sub> represents an OH, OCH<sub>3</sub> or OC<sub>2</sub>H<sub>5</sub> group, or the dotted lines are absent and R<sub>1</sub> represents a hydrogen atom and R<sub>2</sub> represents an OCH<sub>3</sub> group or an OC<sub>2</sub>H<sub>5</sub> group; or B) R<sub>1</sub>, R<sub>4</sub>, and R<sub>6</sub>each represent a hydrogen atom and R<sub>2</sub>, R<sub>3</sub> and R<sub>5</sub> each represent a methyl radical, and the dotted lines are present and represent cis-double bonds or trans-double bonds, and R<sub>7</sub> represents a hydrogen atom and R<sub>8</sub> represents an OH, OCH<sub>3</sub> or OC<sub>2</sub>H<sub>5</sub> bond, or the dotted lines are absent and R<sub>7</sub> represents a hydrogen atom and R<sub>8</sub> represents an OCH<sub>3</sub> group or an OC<sub>2</sub>H<sub>5</sub> group. The inventive compound is an alcoholic derivative or an ether derivative. The invention also relates to the use of at least one compound of formula (I) as an odorant agent. The invention relates to a compound of general formula (I) with or without the double bond illustrated by the dotted line. In formula (I), X is a CHO, CH2OH, CH2OC(O)R or CH(OR)2 group, and R represents a linear or branched C1-C5 alkyl or alkenyl chain. The invention also relates to the synthesis method for said compound, and especially the 6,8-dimethyl-non-7-enal (1) prepared by the hydroformylation of the 5, 7-dimethyl-octa-1,6-diene. The invention further relates to compositions containing the compounds of formula (I). Due to the odorant properties thereof, said compounds are highly useful in perfumery, especially for cosmetic products and household products.
