Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(3-chlorophenyl)acetic acid.
2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(3-chlorophenyl)acetic acid (CAS 339208-90-1) is a high-purity analytical reference standard with the molecular formula C23H18ClNO4 and a molecular weight of 407.85 g/mol.
Structurally, 2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(3-chlorophenyl)acetic acid (C23H18ClNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 407.85 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
