C07G COMPOUNDS OF UNKNOWN CONSTITUTION (sulfonated fats, oils or waxes of undetermined constitution C07C309/62)
Introduced: September 1968
Description
C07G encompasses organic compounds whose precise chemical structure, molecular formula, or constitution has not been definitively established or characterized. This classification serves as a temporary or residual category for substances isolated from natural sources, synthetic mixtures, or incompletely analyzed materials that cannot be assigned to more specific organic chemistry classes. Compounds placed here typically await further chemical analysis, spectroscopic characterization, or structural elucidation. Once the constitution is determined, these compounds would normally be reclassified to appropriate subclasses within C07 (such as C07C for hydrocarbons, C07D for heterocyclic compounds, etc.).
