1-{[(tert-butoxy)carbonyl]amino}-3,3-difluorocyclopentane-1-carboxylic acid CAS 1936649-94-3 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 1-{[(tert-butoxy)carbonyl]amino}-3,3-difluorocyclopentane-1-carboxylic acid.

1-{[(tert-butoxy)carbonyl]amino}-3,3-difluorocyclopentane-1-carboxylic acid (CAS 1936649-94-3) is a high-purity analytical reference standard with the molecular formula C11H17F2NO4 and a molecular weight of 265.25 g/mol.

Structurally, 1-{[(tert-butoxy)carbonyl]amino}-3,3-difluorocyclopentane-1-carboxylic acid (C11H17F2NO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 265.25 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
