Chemical Structure

4-Isobutoxybutan-2-one CAS 31576-33-7 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.

4-Isobutoxybutan-2-one (CAS 31576-33-7), molecular formula C8H16O2 and molecular weight 144.21 g/mol, is a CATO reference standard with documented purity and traceability.

4-Isobutoxybutan-2-one (C8H16O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
