Chemical Structure

Tert-butyl 5-oxopentanoate CAS 192123-41-4 chemical structure

Description

Tert-butyl 5-oxopentanoate (CAS 192123-41-4) is a high-purity analytical reference standard with the molecular formula C9H16O3 and a molecular weight of 172.22 g/mol.

Tert-butyl 5-oxopentanoate (C9H16O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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), Tert-butyl 5-oxopentanoate 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.
