Description

Structurally, 39391-39-4 R76HLW7Z19 Nocardicin A 1-Azetidineacetic acid, 3-(((4-(3-amino-3-carboxypropoxy)phenyl)(hydroxyimino)acetyl)amino)-alpha-(4-hydroxyphenyl)-2-oxo-, (3S-(1(S*),3R*(Z(S*))))- Antibiotic FR 1923 FR-1923-C UNII-R76HLW7Z19 (C23H24N4O9) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 500.46 g/mol, it falls into the moderately-high-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).

39391-39-4 R76HLW7Z19 Nocardicin A 1-Azetidineacetic acid, 3-(((4-(3-amino-3-carboxypropoxy)phenyl)(hydroxyimino)acetyl)amino)-alpha-(4-hydroxyphenyl)-2-oxo-, (3S-(1(S*),3R*(Z(S*))))- Antibiotic FR 1923 FR-1923-C UNII-R76HLW7Z19 (CAS 39391-39-4) is a high-purity analytical reference standard with the molecular formula C23H24N4O9 and a molecular weight of 500.46 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
