Piperonal is an aromatic aldehyde that comes as transparent crystals, C8H6O3, and has a floral odor. It is used as flavoring and in perfume. It can be obtained by oxidation of piperonyl alcohol or the reduction of piperic acid. It is also a minor natural component of the extract of vanilla. It is a common in inexpensive synthetic vanilla flavor and candies.
The aroma of piperonal is described as being similar to that of vanillin and cherry. It finds use as a flavoring and in perfume.
Piperonal has powerful aromatherapeutic qualities which appear to elevate mood and general well-being, and has shown in tests done by the Memorial Sloan-Kettering Cancer Center in New York to reduce the anxiety of patients receiving an MRI by as much as 63 percent
Linalool (pronounced /lɪˈnælɵ.ɒl/) is a naturally-occurring terpene alcohol chemical found in many flowers and spice plants with many commercial applications, the majority of which are based on its pleasant scent (floral, with a touch of spiciness). It has other names such as β-linalool, linalyl alcohol, linaloyl oxide, p-linalool, allo-ocimenol and 2,6-dimethyl-2,7-octadien-6-ol. Linalool is used as a scent in 60-80% of perfumed hygiene products and cleaning agents including soaps, detergents, shampoos, and lotions.[1] It is also used as a chemical intermediate. One common downstream product of linalool is Vitamin E. Additionally, linalool is used by pest professionals as a flea and cockroach insecticide.
Akio Nakamura together with colleagues from the University of Tokyo and T. Hasegawa Co., Ltd in Kawasaki, Japan, claim to have demonstrated that inhaling linalool can reduce stress in lab rats. In a study published in The Journal of Agriculture and Food Chemistry [2] ,
they exposed the animals to stressful conditions and found that those inhaling linalool saw their stress-elevated levels of neutrophils and lymphocytes fall to near-normal levels compared with the controls. Inhaling linalool also reduced the activity of more than 100 genes that "go into overdrive" in stressful situations. The findings could form the basis of new blood tests for identifying fragrances that can soothe stress, the researchers claim [3].

2-ACETYLPYRAZINE
Pyrazine, hygroscopic white solid, is an aromatic nitrogen compound characterized by a ring structure contains 4 carbon atoms with two nitrogen atoms at 1 and 4 positions (paradiazine); melting at 55 - 56 C, boiling at 115 - 116 C. Pyrazine is freely soluble in water. It is fused to form many polycyclic compounds, as useful structures in pharmaceuticals and perfumes. It is a component of the folates (vitamin B compounds) and of the isoalloxazine ring nucleus of flavins. Numerous pyrazine derivatives such as pyrazine polycyclic compounds, alkyl-, alicyclic-, and alkylaryl-substituted compounds, derivatives containing oxygenated functional groups and thio- functional groups in the side-chains are used in biological, drug, flavouring and perfumery industry. 2-Acetylpyrazine is used as a composition of flavouring especially in baked and chocolate properties.

This is the list off my Rose flavored vape....along with of course the ever popular "natural and artificial flavors" which they do no have to disclose due to proprietary recipe reasons. So now I know why this stuff makes me feel so good and why I crave it so!
But seriously....I did this to help you all try and identify the chemicals that might be causing this disagreeable taste...my bet is on Linalool or Piperonal used improperly...ie: bad recipe or poorly manufactured. BTW...all this stuff is made in China. So that was the point about finding USA sourced juices.
