Chemical Structure

1-(Bromomethyl)cyclobutane-1-carboxylic acid CAS 54580-09-5 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.

1-(Bromomethyl)cyclobutane-1-carboxylic acid (CAS 54580-09-5), molecular formula C6H9BrO2 and molecular weight 193.04 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(Bromomethyl)cyclobutane-1-carboxylic acid (C6H9BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 193.04 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.

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.
