Names do not determine the category
A catalog can contain peptide references alongside cofactors, vitamins and other compounds. Their inclusion in one supplier list does not make every item a peptide. The public catalog labels these groups separately.
Review the exact designation
An acronym or informal trade name can be ambiguous. Material identity should be aligned across the specification and supporting documents. Related materials should not inherit claims made for a different class.
Keep the enquiry precise
State the catalog name and the specification you are reviewing. If the chemical form or composition is unclear, identify that gap explicitly. This is more useful than filling missing fields with assumptions.
