Cyclohexylamine

Aminohexahydrobenzene

C6H13N (99.1047938)


Cyclohexylamine is a food contaminant arising from its use as a boiler water additive Cyclohexylamine, also called hexahydroaniline, 1-aminocyclohexane, or aminohexahydrobenzene, is an organic chemical, an amine derived from cyclohexane. It is a clear to yellowish liquid with fishy odor, with melting point of 17.7 °C and boiling point 134.5 °C, miscible with water. Like other amines, it is of mildly alkaline nature, compared to strong bases such as NaOH, but it is a stronger base than its aromatic sister compound aniline, which differs only in that its ring is aromatic. It is flammable, with flash point at 28.6 °C. Explosive mixtures with air can be formed above 26 °C. It is toxic by both ingestion and inhalation; the inhalation itself may be fatal. It readily absorbs through skin, which it irritates. It is corrosive. Cyclohexylamine is listed as an extremely hazardous substance as defined by Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act Food contaminant arising from its use as a boiler water additive CONFIDENCE standard compound; INTERNAL_ID 2441 CONFIDENCE standard compound; INTERNAL_ID 8266 KEIO_ID C114

   

(2R)-2-Hydroxy-2-methylbutanenitrile

(2R)-2-Hydroxy-2-methylbutanenitrile

C5H9NO (99.0684104)


(2r)-2-hydroxy-2-methylbutanenitrile, also known as (R)-butan-2-one cyanohydrin, is a member of the class of compounds known as tertiary alcohols. Tertiary alcohols are compounds in which a hydroxy group, -OH, is attached to a saturated carbon atom R3COH (R not H ) (2r)-2-hydroxy-2-methylbutanenitrile is soluble (in water) and a very weakly acidic compound (based on its pKa). (2r)-2-hydroxy-2-methylbutanenitrile can be found in a number of food items such as poppy, elderberry, banana, and cinnamon, which makes (2r)-2-hydroxy-2-methylbutanenitrile a potential biomarker for the consumption of these food products. This compound belongs to the family of Tertiary Alcohols. These are compounds in which a hydroxy group, -OH, is attached to a saturated carbon atom R3COH (R ≠ H ).

   

2-Piperidinone

5-amino-Lactam-pentanoic acid

C5H9NO (99.0684104)


2-Piperidinone is a derivative of piperidine which is an organic compound. Piperidine is a colorless fuming liquid with an odor described as ammoniacal, pepper-like, the name comes from the genus name Piper, which is the Latin word for pepper. Piperidine is a widely used building block and chemical reagent in the synthesis of organic compounds, including pharmaceuticals.The piperidine structural motif is present in numerous natural alkaloids. These include piperine, which gives black pepper the hot taste. This gave the compound its name. [HMDB] 2-Piperidinone is a derivative of piperidine which is an organic compound.
