Caprolactams are cyclic amides of caproic acid. Caproic acid is the carboxylic acid derived from hexane with the general formula C5H11COOH. Caprolactam is soluble (in water) and a very weakly acidic compound (based on its pKa). Caprolactam is an amine, bitter, and spicy tasting compound found in sunflower, which makes caprolactam a potential biomarker for the consumption of this food product. Caprolactam (CPL) is an organic compound with the formula (CH2)5C(O)NH. This colourless solid is a lactam (a cyclic amide) of caproic acid. Global demand for this compound is approximately 5 million tons per year, and the vast majority is used to make Nylon 6 filament, fiber, and plastics . 1-Aza-2-cycloheptanone 1,6-Hexalactam 1,6-Hexolactam 2-Azacycloheptanone 2-Azepanone 2-Ketohexamethyleneimine 2-Ketohexamethylenimine 2-Oxohexamethyleneimine 2-Oxohexamethylenimine 2-Perhydroazepinone 2H-Azepin-2-one, hexahydro- 2H-Azepin-7-one, hexahydro- 6-amino-hexanoic acid lactam 6-Aminocaproic acid lactam 6-Aminohexanoic acid cyclic lactam 6-Aminohexanoic acid lactam 6-Caprolactam 6-Hexanelactam Akulon Alkamid Amilan cm 1001 Aminocaproic lactam Aza-2-cycloheptanone azepan-2-one Bonamid Capran 77C Caprolactam Caprolactam monomer Caprolattame Caprolon v Capron Chemlon cis-Hexahydro-2-azepinone Cyclohexanone iso-oxime Danamid Durethan BK E-caprolactam E-caprolactum Epsilon-caprolactam Ertalon 6sa Extrom 6N Gamma-caprolactam Grilon Hexahydro-2-azepinone Hexahydro-2H-azepin-2-one Hexannic acid hexanoic acid-6-amino-lactam Hexanolactam Hexanone isoxime Itamid Kaprolit Kaprolon Kapromine Kapron Maranyl F 114 Metamid Miramid H 2 Nipro (I) Nylon A1035sf Omega-caprolactum Orgamid rmnocd Orgamide Perhydroazepin-2-one Plaskin 8200 Plaskon 201 Polyamide pk 4 Relon p Renyl MV Sipas 60 Spencer 401 Spencer 601 Steelon Stilon Stylon Tarlon x-a Tarlon XB Tarnamid T 2 Tarnamid T 27 TNK 2G5 Torayca N 6 U-caprolactam Ultramid BMK Vidlon Widlon Zytel 211 C6H11NO 113.1576 113.084063979 azepan-2-one caprolactam 105-60-2 O=C1CCCCCN1 InChI=1S/C6H11NO/c8-6-4-2-1-3-5-7-6/h1-5H2,(H,7,8) JBKVHLHDHHXQEQ-UHFFFAOYSA-N belongs to the class of organic compounds known as caprolactams.
