Chemical Structure

Isobutyramide CAS 563-83-7 chemical structure

Description

Isobutyramide (CAS 563-83-7) is a high-purity analytical reference standard with the molecular formula C4H9NO and a molecular weight of 87.12 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, Isobutyramide is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 87.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
