Overview

3-methyl-2,4,6-trinitrophenol (CAS 602-99-3) is a nitroaromatic explosive compound with high detonation sensitivity and acute toxicity properties. This highly energetic material belongs to the family of polynitrophenols, characterized by three nitro groups (-NO2) attached to a phenol ring with an additional methyl substituent. The compound exhibits typical properties of primary explosives, demonstrating extreme sensitivity to impact, friction, and heat, which necessitates specialized handling protocols and storage conditions. Its molecular structure, with a molecular weight of 243.13 g/mol and formula C7H5N3O7, contributes to its classification as Explosive 1.1 under GHS guidelines, indicating mass explosion hazards. The substance presents significant safety concerns beyond its explosive nature, classified as Acute Tox. 4 through multiple exposure routes including oral, dermal, and inhalation pathways. The combination of GHS01 (exploding bomb) and GHS07 (exclamation mark) pictogrammes reflects both its explosive hazard and acute toxicity profile. Its ADR Class 1 classification requires strict transportation regulations and specialized logistics handling. Industrial applications primarily focus on specialized explosive formulations, research and development of energetic materials, and controlled demolition applications where precise detonation characteristics are required. Like related compounds such as 2,4,6-trinitrobenzene-1,3-diol, it serves specific roles in pyrotechnic research and military applications. The compound may also find limited use in analytical chemistry as a reference standard for explosive detection methodologies. OYSI maintains strict compliance with all European regulations for the distribution of this controlled explosive material, ensuring proper documentation and safety protocols for qualified industrial customers.
