Chemical Structure
Description
CATO supplies 4-Bromo-1,2,3,6,7,8-hexahydro-as-indacene (CAS 2420508-25-2), a certified reference material (molecular formula C12H13Br, MW 237.14 g/mol) for analytical method development and quality control.
Structurally, 4-Bromo-1,2,3,6,7,8-hexahydro-as-indacene (C12H13Br) contains bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 237.14 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
