Chemical Structure

2-Acetylbutyrolactone-13C4 84508-47-4 CAS 84508-47-4 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Acetylbutyrolactone-13C4 84508-47-4 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

2-Acetylbutyrolactone-13C4 84508-47-4 (CAS 84508-47-4), molecular formula C2[13C]4H8O3 and molecular weight 132.10 g/mol, is a CATO reference standard with documented purity and traceability.

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.
