Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-3,3’-Dibromo-2,2’-bis(methoxymethoxy)-1,1’-binaphthalene.
(S)-3,3’-Dibromo-2,2’-bis(methoxymethoxy)-1,1’-binaphthalene (CAS 142010-87-5) is a high-purity analytical reference standard with the molecular formula C24H20Br2O4 and a molecular weight of 532.22 g/mol.
The molecular framework of (S)-3,3’-Dibromo-2,2’-bis(methoxymethoxy)-1,1’-binaphthalene (C24H20Br2O4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
