No published acute toxicity value was found for this substance in the sources we read. On a document, Section 11 would print unsourced — inference candidate rather than an estimate.
This page is the evidence. The document is the deliverable.
Everything above is free and stays free. For $5 the same sourced values are assembled into a 16-section safety data sheet and a print-ready GHS label carrying your company details in Section 1.
