Chemical Structure

2-((tert-Butoxycarbonyl)amino)-2-(2,3-dihydro-1H-inden-2-yl)acetic acid CAS 155172-73-9 chemical structure

Description

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.

2-((tert-Butoxycarbonyl)amino)-2-(2,3-dihydro-1H-inden-2-yl)acetic acid (CAS 155172-73-9) is a high-purity analytical reference standard with the molecular formula C16H21NO4 and a molecular weight of 291.34 g/mol.

Structurally, 2-((tert-Butoxycarbonyl)amino)-2-(2,3-dihydro-1H-inden-2-yl)acetic acid (C16H21NO4) contains a flavonoid core, 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 291.34 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).

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.
