Chemical Structure
Description
The occurrence of 1-(4-Nitrophenyl)butane-1,3-dione is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(4-Nitrophenyl)butane-1,3-dione (CAS 4023-82-9), molecular formula C10H9NO4 and molecular weight 207.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(4-Nitrophenyl)butane-1,3-dione (C10H9NO4) 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 207.18 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.
