Chemical Structure
Description
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.
1,3-Bis(2'bromo-4'-cyano-phenoxy)propane (CAS 93840-60-9) is a high-purity analytical reference standard with the molecular formula C17H12Br2N2O2 and a molecular weight of 436.10 g/mol.
Structurally, 1,3-Bis(2'bromo-4'-cyano-phenoxy)propane (C17H12Br2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 436.10 g/mol, it falls into the moderately-high-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).
As a certified reference material (CRM), 1,3-Bis(2'bromo-4'-cyano-phenoxy)propane 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.
