1)通過查詢Pubchemical 未檢索到有關(guān)DIPEA的"HSDB"數(shù)據(jù)庫信息;2)ECHA官網(wǎng)的"REACH registered substance factsheets"可查閱到DIPEA的"Toxicology inforamtion",顯示“No repeated dose toxicity study is available for ethyldiisopropylamine (EDIPA). However, two related structural anologues, trimethylamine (CAS No. 75-50-3 ) and triethylamine (CAS No. 121-44-8) have been tested by the oral or the inhalation routes.。。。 in a subchronic inhalation toxicity study with triethylamine, the NOAEC was higher than 247 ppm (1022 mg/m3)”,因此,個人覺得DIPEA限度制定可參考ICH 3Q附錄的三乙胺的NOEL為247ppm計算限度為6250ppm. https://echa.europa.eu/registrat ... dossier/13609/7/6/1 |
