CH2NH3

CH2NH3 is a chemical formula that denotes a compound containing one carbon atom, one nitrogen atom, and five hydrogen atoms. As a standalone formula, it does not correspond to a widely recognized neutral molecule with a defined structure under standard conditions. In many contexts, CH2NH3 appears only as an atom-count shorthand or as part of computational or theoretical inputs, where the exact connectivity, geometry, and charge state are specified separately.

Because a neutral molecule with that exact formula is not well established in common chemistry, the properties of CH2NH3 are not defined without additional structural information. In practice, related but distinct species with similar atom counts include methanimine (CH2NH) and methylamine (CH3NH2), which have well-characterized structures and reactivities. Protonated or ionized forms of related compounds are common in gas-phase and solution chemistry, but these species are different from the neutral CH2NH3 formulation.

If CH2NH3 is encountered in a database, publication, or computational output, it is important to consult the context to determine whether it denotes a specific charged species, a fragment, or a misnotation. Accurate interpretation typically requires accompanying structural data, such as connectivity, charge, and multiplicity.
