Overview

7,10-diazoniatricyclo[8.4.0.02,7]tetradeca-1(14),2,4,6,10,12-hexaene dihydroxide (CAS 94021-76-8) is a tricyclic diazonia compound with significant toxicity and specialized industrial applications. This complex organic compound features a unique tricyclic structure containing two nitrogen cations and hydroxide counterions, resulting in a molecular formula of C12H14N2O2 and a molecular weight of 218.25 g/mol. The European chemical identification number EC 301-467-6 classifies this substance under strict regulatory oversight due to its hazardous properties. The compound exhibits severe toxicity characteristics, classified under multiple acute toxicity categories (Acute Tox. 2 and 4) with ADR transport classification 6.1 for toxic substances. Its hazard profile includes specific target organ toxicity for both single and repeated exposure (STOT SE 3, STOT RE 1), along with skin and eye irritation properties and skin sensitization potential. The GHS pictograms GHS06, GHS08, and GHS09 indicate its toxic, health hazard, and environmentally dangerous nature, warranting the signal word "Danger" on safety documentation. Industrial applications typically involve specialized chemical synthesis processes where the compound's unique tricyclic diazonia structure provides specific reactivity patterns. It serves as an intermediate in pharmaceutical manufacturing and advanced organic synthesis protocols. The compound shares certain structural characteristics with simpler aromatic nitrogen compounds like N-methylaniline, though its tricyclic nature provides distinctly different chemical behavior. Safety protocols require specialized handling procedures, appropriate personal protective equipment, and controlled storage conditions to prevent exposure risks. Environmental considerations are paramount given its classification profile. OYSI maintains availability of this specialized chemical for qualified industrial customers requiring documented technical applications.
