Chemical Structure

Isobutyl Propionate CAS 540-42-1 chemical structure

Description

The occurrence of Isobutyl Propionate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Isobutyl Propionate (CAS 540-42-1), molecular formula C7H14O2 and molecular weight 130.18 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H14O2, Isobutyl Propionate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 130.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
