2,5-Hexanedione: HSNO Approval: HSR002760 Approved with controls

SYMPTOMS: This compound may cause irritation of the skin and eyes. It may also cause irritation of the mucous membranes and upper respiratory tract. Exposure to high concentrations of this compound may cause narcosis. It is neurotoxic. It may cause peripheral neuropathy. Discoloration of the skin has been reported. Chronic exposure may produce severe neurologic damage and testicular germinal cell damage. It may affect formed elements of blood after prolonged exposure. Chronic exposure may also cause severe impairment of the central and peripheral nervous systems, the testes and circulating elements in the blood.

Drugs that inhibit cholinesterases. The neurotransmitter ACETYLCHOLINE is rapidly hydrolyzed, and thereby inactivated, by cholinesterases. When cholinesterases are inhibited, the action of endogenously released acetylcholine at cholinergic synapses is potentiated. Cholinesterase inhibitors are widely used clinically for their potentiation of cholinergic inputs to the gastrointestinal tract and urinary bladder, the eye, and skeletal muscles; they are also used for their effects on the heart and the central nervous system.

Reagents with two reactive groups, usually at opposite ends of the molecule, that are capable of reacting with and thereby forming bridges between side chains of amino acids in proteins; the locations of naturally reactive areas within proteins can thereby be identified; may also be used for other macromolecules, like glycoproteins, nucleic acids, or other.

Toxic substances from microorganisms, plants or animals that interfere with the functions of the nervous system. Most venoms contain neurotoxic substances. Myotoxins are included in this concept.

Used as a solvent for cellulose acetate, roll-coating inks, lacquers, and stains; as an intermediate for pharmaceuticals and photographic chemicals; and in electroplating; [NTP]
