4-Ethynyl-1-((tetrahydro-2H-pyran-4-yl)methyl)-1H-pyrazole CAS 2098072-57-0

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-Ethynyl-1-((tetrahydro-2H-pyran-4-yl)methyl)-1H-pyrazole is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 190.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

4-Ethynyl-1-((tetrahydro-2H-pyran-4-yl)methyl)-1H-pyrazole (CAS 2098072-57-0), molecular formula C11H14N2O and molecular weight 190.24 g/mol, is a CATO reference standard with documented purity and traceability.

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.
