Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-1-(3,6-Dibromo-9H-carbazol-9-yl)-3-((3-methoxyphenyl)amino)propan-2-ol.
(R)-1-(3,6-Dibromo-9H-carbazol-9-yl)-3-((3-methoxyphenyl)amino)propan-2-ol (CAS 1235481-41-0) is a high-purity analytical reference standard with the molecular formula C22H20Br2N2O2 and a molecular weight of 504.21 g/mol.
The molecular framework of (R)-1-(3,6-Dibromo-9H-carbazol-9-yl)-3-((3-methoxyphenyl)amino)propan-2-ol (C22H20Br2N2O2) is characterized by a steroid core, an amide group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), (R)-1-(3,6-Dibromo-9H-carbazol-9-yl)-3-((3-methoxyphenyl)amino)propan-2-ol 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.
