Chemical Structure
Description
7-bromo-1,2,2-trimethyl-1,2,3,4-tetrahydroquinoxaline (CAS 1505167-77-0), molecular formula C11H15BrN2 and molecular weight 255.15 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7-bromo-1,2,2-trimethyl-1,2,3,4-tetrahydroquinoxaline (C11H15BrN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. 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 255.15 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 7-bromo-1,2,2-trimethyl-1,2,3,4-tetrahydroquinoxaline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
