miscellaneous and its Impurities
Miscellaneous Chemicals typically refers to a broad and diverse category of chemical substances that don't neatly fit into more specific classifications like commodity chemicals, specialty chemicals, or fine chemicals. Reference standards of Miscellaneous API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
