Chemical Structure
Description
(E)-3-(4-Nitrophenyl)acrylic acid (CAS 882-06-4), molecular formula C9H7NO4 and molecular weight 193.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-3-(4-Nitrophenyl)acrylic acid (C9H7NO4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 193.16 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (E)-3-(4-Nitrophenyl)acrylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
