2-(1-(Tert-butoxycarbonyl)-3-hydroxyazetidin-3-yl)-2,2-difluoroacetic acid CAS 2138336-44-2 chemical structure

Description

Structurally, 2-(1-(Tert-butoxycarbonyl)-3-hydroxyazetidin-3-yl)-2,2-difluoroacetic acid (C10H15F2NO5) 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 267.23 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.

CATO supplies 2-(1-(Tert-butoxycarbonyl)-3-hydroxyazetidin-3-yl)-2,2-difluoroacetic acid (CAS 2138336-44-2), a certified reference material (molecular formula C10H15F2NO5, MW 267.23 g/mol) for analytical method development and quality control.

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.
