Chemical Structure

tert-Butyl 2-bromopentanoate CAS 55424-42-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 237.13 g/mol gives tert-Butyl 2-bromopentanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

tert-Butyl 2-bromopentanoate (CAS 55424-42-5) is a high-purity analytical reference standard with the molecular formula C9H17BrO2 and a molecular weight of 237.13 g/mol.

tert-Butyl 2-bromopentanoate (C9H17BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 2-bromopentanoate 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.
