摘要：
The present invention relates to [1] a method for keeping a quality of 2-methyl-3-(3,4-methylenedioxyphenyl)propanal useful as a perfume, which comprises incorporating from 50 to 3000 ppm of 1-acetyl-3,4-methylenedioxybenzene in the 2-methyl-3-(3,4-methylenedioxyphenyl)propanal; [2] a process for producing 2-methyl-3-(3,4-methylenedioxyphenyl)propanal having a content range from 50 to 3000 ppm of 1-acetyl-3,4-methylenedioxybenzene; and [3]2-methyl-3-(3,4-methylenedioxyphenylpropanal having a content range from 50 to 3000 ppm of of 1-acetyl-3,4-methylenedioxybenzene.
