Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
3-Methyl-2-(prop-2-yn-1-yl)-2,4,5,6-tetrahydrocyclopenta[c]pyrazole (CAS 623571-91-5) is a high-purity analytical reference standard with the molecular formula C10H12N2 and a molecular weight of 160.22 g/mol.
The molecular framework of 3-Methyl-2-(prop-2-yn-1-yl)-2,4,5,6-tetrahydrocyclopenta[c]pyrazole (C10H12N2) 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. 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.
