Chemical Structure
Description
As a certified reference material (CRM), [1-(4-chlorophenyl)-1H-1,2,3-triazol-4-yl]methanol 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.
CATO supplies [1-(4-chlorophenyl)-1H-1,2,3-triazol-4-yl]methanol (CAS 133902-66-6), a certified reference material (molecular formula C9H8ClN3O, MW 209.63 g/mol) for analytical method development and quality control.
[1-(4-chlorophenyl)-1H-1,2,3-triazol-4-yl]methanol (C9H8ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
