Chemical Structure

2-Isopropylacetoacetate ethyl ester CAS 1522-46-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 172.22 g/mol gives 2-Isopropylacetoacetate ethyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Isopropylacetoacetate ethyl ester (CAS 1522-46-9), molecular formula C9H16O3 and molecular weight 172.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Isopropylacetoacetate ethyl ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
