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.
2,4-Dimethyl-7,8,9,10-tetrahydropyrido[4',3':3,4]pyrazolo[1,5-a]pyrimidine (CAS 1706464-23-4) is a high-purity analytical reference standard with the molecular formula C11H14N4 and a molecular weight of 202.26 g/mol.
The molecular framework of 2,4-Dimethyl-7,8,9,10-tetrahydropyrido[4',3':3,4]pyrazolo[1,5-a]pyrimidine (C11H14N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2,4-Dimethyl-7,8,9,10-tetrahydropyrido[4',3':3,4]pyrazolo[1,5-a]pyrimidine 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.
