Furaldehyde, also known as furfural, is a heterocyclic organic compound with the formula C4H3OCHO. It is a colorless liquid that is produced from the dehydration of pentoses, such as xylose and arabinose, which are found in plant materials like corncobs, oat hulls, and rice hulls. Furaldehyde is used as a solvent, a flavoring agent, and a precursor to other chemicals. It is also used in the production of resins, polymers, and pharmaceuticals. Furaldehyde has a wide range of effects on human health and the environment. It is a known irritant to the skin, eyes, and respiratory system. It can also be toxic if ingested or inhaled in large amounts. Furaldehyde is studied for its potential use in the production of biofuels and other renewable energy sources. Its importance is further demonstrated by its use as an indicator of food quality and freshness.'

| Methemoglobinemia The presence of methemoglobin in the blood, resulting in cyanosis. A small amount of methemoglobin is present in the blood normally, but injury or toxic agents convert a larger proportion of hemoglobin into methemoglobin, which does not function reversibly as an oxygen carrier. Methemoglobinemia may be due to a defect in the enzyme NADH methemoglobin reductase (an autosomal recessive trait) or to an abnormality in hemoglobin M (an autosomal dominant trait).
