安全性と法規制
| GHS 分類 | This chemical does not meet GHS hazard criteria for 87.5% (7 of 8) of all reports.WarningH315 (12.5%): Causes skin irritation [Warning Skin corrosion/irritation]P261, P264, P264+P265, P271, P280, P302+P352, P304+P340, P305+P351+P338, P319, P321, P332+P317, P337+P317, P362+P364, P403+P233, P405, and P501 (click each P-code to see the statement)Aggregated GHS information provided per 8 reports by companies from 2 notifications to the ECHA C&L Inventory. Each notification may be associated with multiple companies. |
|---|---|
| 規制情報 | D-Tryptophan: Does not have an individual approval but may be used under an appropriate group standard |
| 火災危険 | Flash point data are not available for this chemical, but it is probably combustible. (NTP, 1992) |
| 有害性の概要 | Causes altered sleep time (including change in righting reflex), dyspnea, and decreased body temperature in intraperitoneal lethal-dose studies of rats (LD50 = 4,289 mg/kg)[RTECS] May cause irritation[Alfa Aesar MSDS] |
| 反応性グループ | Salts, Acidic |
| Reactivity Profile | Acidic salts, such as D(+)-TRYPTOPHAN, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions. |
| Air and Water Reactions | Slightly soluble in water. |
| Hazard Classes and Categories | Skin Irrit. 2 (12.5%) |
| 消火 | Fires involving this compound should be controlled using a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992) |
| 応急処置 | 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. |
用途
使用
