Chemical Structure
Description
The occurrence of tert-butyl 2-bromo-2-cyclopropylacetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
tert-butyl 2-bromo-2-cyclopropylacetate (CAS 2059993-81-4), molecular formula C9H15BrO2 and molecular weight 235.12 g/mol, is a CATO reference standard with documented purity and traceability.
tert-butyl 2-bromo-2-cyclopropylacetate (C9H15BrO2) 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-bromo-2-cyclopropylacetate 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.
