3'-アミノ-4'-エトキシアセトアニリド

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: Should a spill occur while you are handling this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with 60-70% ethanol and transfer the dampened material to a suitable container. Use absorbent paper dampened with 60-70% ethanol to pick up any remaining material. Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol 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.

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with a combination filter cartridge, i.e. organic vapor/acid gas/HEPA (specific for organic vapors, HCl, acid gas, SO2 and a high efficiency particulate filter).

A bioassay of 3-amino-4-ethoxyacetanilide for possible carcinogenicity was conducted using Fischer 344 rats and B6C3F1 mice. 3-Amino-4-ethoxyacetanilide was admin in the feed, at either of two concentrations, to groups of approximately 50 male and 50 female animals of each species. The dietary concentrations used in the chronic bioassay for low and high dose rats were 0.4 and 1.5%, respectively. The dietary concentrations used for the low and high dose mice were 0.4 and 0.8%, respectively. After a 78 wk period of chemical administration, observation of rats continued for up to 35 wk and observation of mice continued for up to 18 wk. For each species, 50 animals of each sex were placed on test as controls for low dose groups and approximately 50 animals of each sex were placed on test as controls for high dose groups. ... Under the conditions of this bioassay, 3-amino-4-ethoxyacetanilide was carcinogenic in male B6C3F1 mice, causing follicular cell carcinomas of the thyroid gland. ... /Under the conditions of this study, 3-amino-4-ethoxyacetanilide was not carcinogenic in female B6C3F1 mice or in male or in female F344/N rats. {
