Description
As a certified reference material (CRM), 1-Bromo-2-(tert-butyl)-3-cyclopropoxybenzene 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.
1-Bromo-2-(tert-butyl)-3-cyclopropoxybenzene (CAS 1243368-94-6), molecular formula C13H17BrO and molecular weight 269.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Bromo-2-(tert-butyl)-3-cyclopropoxybenzene (C13H17BrO) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 269.18 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
