Safety
| OxymaPure | HOBt |
| GHS classification of OxymaPure is Category 4 of acute toxicity (LD50 of 300-2000mg/kg) | Hydrazine used in manufacturing of HOBt is highly toxic and readily absorbed by oral, dermal or inahalation exposure. Long-term studies with laboratory animals indicate that hydrazine is mutagenic and carcinogenic. Hydrazine traces are usually present in commercial batches of HOBt ( reference) |
| Acute dermal irritation: In consideration of calculated Primary Irritation index, OxymaPure is categorized as a “Slight” dermal irritant. | |
| Nitrozamine safety. OxymaPure is made by nitrosation of ethyl 2-cyanoacetate, in the presence of sodium nitrite, however manufacturing procedure exclude formations of Nitrosamines during the synthesis which is confirmed by analytical testing. |
