Chemical Structure
Description
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 supplies 1-(5-Bromo-2-ethoxyphenyl)-1H-tetrazole (CAS 1174874-75-9), a certified reference material (molecular formula C9H9BrN4O, MW 269.10 g/mol) for analytical method development and quality control.
1-(5-Bromo-2-ethoxyphenyl)-1H-tetrazole (C9H9BrN4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 1-(5-Bromo-2-ethoxyphenyl)-1H-tetrazole 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.
