Danger

H227: Combustible liquid [Warning Flammable liquids]

Chemical: 2,5-Hexanedione

Hazard Traits - Reproductive Toxicity

2,5-Hexanedione is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of 2,5-Hexanedione are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)

Status: Active Update: 24-01-2023 https://echa.europa.eu/registration-dossier/-/registered-dossier/17623

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.

A mild irritant; High concentrations may cause narcosis; [Merck Index] Causes degenerative changes to brain and nerves in 15-week intermittent dermal studies of rats; Causes neurotoxicity and male reproductive changes in repeated dose studies; [RTECS] A skin and strong eye irritant; Prolonged or repeated exposure may cause serious organ injury; May cause impaired fertility; Harmful by ingestion and inhalation; [Alfa Aesar MSDS]

Flammable liquids - Category 4

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SMALL SPILLS AND LEAKAGE: If you should spill this chemical, use absorbent paper to pick up all liquid spill material. Seal the absorbent paper, as well as any of your clothing which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Wash any surfaces you may have contaminated with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

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.
