Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-methyl-[1,2,4]triazolo[3,4-a]phthalazine.
3-methyl-[1,2,4]triazolo[3,4-a]phthalazine (CAS 20062-41-3), molecular formula C10H8N4 and molecular weight 184.20 g/mol, is a CATO reference standard with documented purity and traceability.
3-methyl-[1,2,4]triazolo[3,4-a]phthalazine (C10H8N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 3-methyl-[1,2,4]triazolo[3,4-a]phthalazine 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.
