Chemical Structure
Description
The occurrence of TRANS-1-(TERT-BUTOXYCARBONYL)-4-ETHYLPYRROLIDINE-3-CARBOXYLIC ACID 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.
TRANS-1-(TERT-BUTOXYCARBONYL)-4-ETHYLPYRROLIDINE-3-CARBOXYLIC ACID (CAS 1268520-70-2) is a high-purity analytical reference standard with the molecular formula C12H21NO4 and a molecular weight of 243.30 g/mol.
The molecular framework of TRANS-1-(TERT-BUTOXYCARBONYL)-4-ETHYLPYRROLIDINE-3-CARBOXYLIC ACID (C12H21NO4) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
