4-Ethynyl-1-isopropyl-1H-pyrazole CAS 1354706-51-6

Description

4-Ethynyl-1-isopropyl-1H-pyrazole (CAS 1354706-51-6), molecular formula C8H10N2 and molecular weight 134.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-Ethynyl-1-isopropyl-1H-pyrazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 134.18 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).

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.

CATO manufactures 4-Ethynyl-1-isopropyl-1H-pyrazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
