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-[(5-bromo-2-methoxyphenyl)methyl]-1h-1,2,3,4-tetrazole.
5-[(5-bromo-2-methoxyphenyl)methyl]-1h-1,2,3,4-tetrazole (CAS 1247522-13-9) is a high-purity analytical reference standard with the molecular formula C9H9BrN4O and a molecular weight of 269.10 g/mol.
5-[(5-bromo-2-methoxyphenyl)methyl]-1h-1,2,3,4-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).
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), 5-[(5-bromo-2-methoxyphenyl)methyl]-1h-1,2,3,4-tetrazole 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.
