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 5,7-Dibromo-6-methyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-indazole.
5,7-Dibromo-6-methyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-indazole (CAS 1973503-49-9), molecular formula C14H20Br2N2OSi and molecular weight 420.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5,7-Dibromo-6-methyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-indazole (C14H20Br2N2OSi) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5,7-Dibromo-6-methyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-indazole 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.
