(2R,3S)-2-(2-(tert-butoxy)-2-oxoethyl)-3-methylpentanoic acid CAS 692778-50-0

Description

Compared with other compounds in its class, the molecular weight of 230.30 g/mol gives (2R,3S)-2-(2-(tert-butoxy)-2-oxoethyl)-3-methylpentanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(2R,3S)-2-(2-(tert-butoxy)-2-oxoethyl)-3-methylpentanoic acid (CAS 692778-50-0), molecular formula C12H22O4 and molecular weight 230.30 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (2R,3S)-2-(2-(tert-butoxy)-2-oxoethyl)-3-methylpentanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 230.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
