Chemical Structure
Description
The molecular framework of 9- (Bromomethyl) - 2, 3, 6, 7- tetramethoxyphenanthrene (C19H19BrO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
9- (Bromomethyl) - 2, 3, 6, 7- tetramethoxyphenanthrene (CAS 1150647-83-8), molecular formula C19H19BrO4 and molecular weight 391.26 g/mol, is a CATO reference standard with documented purity and traceability.
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), 9- (Bromomethyl) - 2, 3, 6, 7- tetramethoxyphenanthrene 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.
