Chemical Structure

1-(prop-2-yn-1-yl)cyclobutane-1-carboxylic acid CAS 1423032-50-1 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.

1-(prop-2-yn-1-yl)cyclobutane-1-carboxylic acid (CAS 1423032-50-1) is a high-purity analytical reference standard with the molecular formula C8H10O2 and a molecular weight of 138.16 g/mol.

1-(prop-2-yn-1-yl)cyclobutane-1-carboxylic acid (C8H10O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
