2,5,7-Trimethyl-6-[(2E)-3-phenylprop-2-en-1-yl]pyrazolo[1,5-a]pyrimidine CAS 685107-98-6

Description

As a certified reference material (CRM), 2,5,7-Trimethyl-6-[(2E)-3-phenylprop-2-en-1-yl]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.

2,5,7-Trimethyl-6-[(2E)-3-phenylprop-2-en-1-yl]pyrazolo[1,5-a]pyrimidine (CAS 685107-98-6), molecular formula C18H19N3 and molecular weight 277.36 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,5,7-Trimethyl-6-[(2E)-3-phenylprop-2-en-1-yl]pyrazolo[1,5-a]pyrimidine (C18H19N3) 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.

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.
