CH3C3H7NH

CH3C3H7NH represents a chemical formula that is likely incomplete or contains a typo, making it difficult to definitively identify a specific compound. The notation suggests a molecule containing a methyl group (CH3), a propyl group (C3H7), and an amine functional group (NH). However, the way these groups are connected is not clearly specified.

If the intention was to represent an amine where a methyl group and a propyl group are attached to a nitrogen atom, this would be an N-methyl-N-propylamine. Depending on whether the propyl group is n-propyl, isopropyl, or another isomer, the formula would be more precisely written. For example, N-methyl-n-propylamine would be CH3NHCH2CH2CH3.

Alternatively, the formula might be an attempt to represent a molecule with a branched hydrocarbon chain and an amine. Without further clarification on the connectivity of the atoms, it's impossible to assign a unique IUPAC name or CAS number. The formula is too ambiguous to be a standard representation of a chemical compound. Therefore, CH3C3H7NH itself does not refer to a single, well-defined chemical substance in common chemical nomenclature.
