Chemical Structure

5-(tert-Butoxy)-5-oxopentanoic Acid CAS 63128-51-8 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.

5-(tert-Butoxy)-5-oxopentanoic Acid (CAS 63128-51-8) is a high-purity analytical reference standard with the molecular formula C9H16O4 and a molecular weight of 188.22 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 5-(tert-Butoxy)-5-oxopentanoic Acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
