Description

Compared with other compounds in its class, the molecular weight of 216.27 g/mol gives (S)-tert-butyl 2-acetoxy-3-methylbutanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(S)-tert-butyl 2-acetoxy-3-methylbutanoate (CAS 380886-48-6) is a high-purity analytical reference standard with the molecular formula C11H20O4 and a molecular weight of 216.27 g/mol.

Structurally, (S)-tert-butyl 2-acetoxy-3-methylbutanoate (C11H20O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 216.27 g/mol, it falls into the medium-molecular-weight range. 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.

As a certified reference material (CRM), (S)-tert-butyl 2-acetoxy-3-methylbutanoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
