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 6,7-difluoro-1-methyl-1H-1,3-benzodiazol-5-ol (CAS 1394947-68-2), a certified reference material (molecular formula C8H6F2N2O, MW 184.14 g/mol) for analytical method development and quality control.
Structurally, 6,7-difluoro-1-methyl-1H-1,3-benzodiazol-5-ol (C8H6F2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 184.14 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 6,7-difluoro-1-methyl-1H-1,3-benzodiazol-5-ol 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.
