1 | Explosives | Not classified |
- |
- | - | Because a marketed product contains a stabilizer, the classification "Not classified" is conceivable, though it contains a chemical group (N-O) associated with explosive properties. Besides, the sub-categorization is not possible because a pure form is an unstable substance (Many alkyl nitrites are thermally unstable and may readily decompose or explode on heating. Methyl nitrite explodes more violently than ethyl nitrite. Lower alkyl nitrites have been known to decompose and burst the container, even in refrigerated storage.) (Bretherick (7th, 2007)). |

There is information about nitrites that inhalation of high concentration relaxes smooth muscle, and the consequent intense peripheral vasodilation produces flushing, a fall in blood pressure, and a reflex increase in heart rate to maintain perfusion of vital organs (NIDA Research Monograph 83 (1988)), and that nervous system symptoms such as a headache, dizziness, ataxia, syncope, sedative action, a sense of weakness are observed (meeting material of the Committee on Designated Substances, Pharmaceutical Affairs and Food Sanitation Council, MHLW (2006)), therefore, it was classified in Category 1 (cardiovascular system, nervous system). Furthermore, effects of this substance on blood are also indicated from the information that nitro compounds such as nitrate and nitrite cause methemoglobinemia to animals (PATTY (5th, 2001)), side effects of medical isopentyl nitrite includes methemoglobinemia, cyanosis, and hemolytic anemia (Ethical pharmaceuticals (2010)), and butyl nitrites have a feature of methemoglobin formation in mice (NIDA Research Monograph 83 (1988)), therefore, it was classified in Category 1 (blood system). |
