CH24COOH2

CH24COOH2 is not a recognized chemical formula in standard nomenclature. The presence of a "2" subscript following a carboxylic acid group (COOH) is ambiguous and does not conform to IUPAC or common chemical naming conventions. A carboxylic acid group is represented as -COOH. If the intention was to indicate a dicarboxylic acid, the formula would typically be written to show two such groups, for example, HOOC-R-COOH, where R represents a carbon chain. Alternatively, if the "2" refers to the number of carboxylic acid groups within a larger molecule, it would be incorporated into the overall formula and name of that specific compound. Without further context or clarification, CH24COOH2 cannot be definitively identified or described as a specific chemical substance. It is possible this notation is a typo or represents a non-standard or hypothetical structure.
