Metabolite Identification
Common NameCaffeic acid 4-O-sulfate
DescriptionCaffeic acid 4-O-sulfate (CAS: 1213651-94-5) is a polyphenol metabolite detected in biological fluids (PMID: 20428313 ). Caffeic acid sulfate was found to be elevated in rat urine after whole rye consumption which makes this compound a potential urinary biomarker of whole grain intake (PMID: 26862900 ).
