Aggregated GHS information provided per 4 reports by companies from 4 notifications to the ECHA C&L Inventory. Each notification may be associated with multiple companies.

SYMPTOMS: Symptoms of exposure to related compounds are skin and gastrointestinal tract irritation, sensitization, blistering, nausea, vomiting, diarrhea, urinary tract irritation, initial excitement, convulsions and central nervous system depression. (NTP, 1992)

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 a spill of this chemical occurs, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with acetone and transfer the dampened material to a suitable container. Use absorbent paper dampened with acetone to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing 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.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

/GENOTOXICITY/ 2,4,5-Trimethoxy benzaldehyde (TMB) was tested for mutagenicity in the Salmonella/microsome preincubation assay using a protocol approved by the National Toxicology Program. TMB was tested at doses of 0, 100, 333, 1000, 3333, and 10,000 ug/plate in four Salmonella typhimurium strains (TA98, TA100, TA1535, and TA1537) in the presence and absence of Aroclor-induced rat and/or hamster liver S9. TMB was negative in these tests and the highest ineffective dose level tested (not causing formation of a precipitate) in any Salmonella tester strain was 3333 ug/plate.[Zeiger E et al; Environ Mutagen 9:1-110 (1987)]

Benzaldehyde, 2,4,5-trimethoxy-: ACTIVE

Asarylaldehyde was identified as an active component from the distillate of the essential oil of the root of Indian calamus. Asarylaldehyde was attractive to male & female Mediterranean fruit flies & female oriental fruit flies. Of the 3 positional isomers of asarylaldehyde only the 3,4,5-isomer showed activity.

UV (355 NM) irradiation of trans-isoasarone formed cis-isoasarone and asaronaldehyde.
