Chemical Structure
Description
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.
(R)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-4-methylpentanoic acid (CAS 882183-86-0) is a high-purity analytical reference standard with the molecular formula C22H25NO4 and a molecular weight of 367.44 g/mol.
Structurally, (R)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-4-methylpentanoic acid (C22H25NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 367.44 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
