Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-[2,4-Dichloro-5-(2-methoxyethoxy)phenyl]-5-(3,4-dichlorophenyl)-1H-1,2,3,4-tetrazole.
1-[2,4-Dichloro-5-(2-methoxyethoxy)phenyl]-5-(3,4-dichlorophenyl)-1H-1,2,3,4-tetrazole (CAS 338961-62-9), molecular formula C16H12Cl4N4O2 and molecular weight 434.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-[2,4-Dichloro-5-(2-methoxyethoxy)phenyl]-5-(3,4-dichlorophenyl)-1H-1,2,3,4-tetrazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 434.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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), 1-[2,4-Dichloro-5-(2-methoxyethoxy)phenyl]-5-(3,4-dichlorophenyl)-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.
