1-Ethyl-4-ethynyl-5-methyl-1H-pyrazole CAS 1354706-48-1

Description

Compared with other compounds in its class, the molecular weight of 134.18 g/mol gives 1-Ethyl-4-ethynyl-5-methyl-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-Ethyl-4-ethynyl-5-methyl-1H-pyrazole (CAS 1354706-48-1), a certified reference material (molecular formula C8H10N2, MW 134.18 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-Ethyl-4-ethynyl-5-methyl-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 1-Ethyl-4-ethynyl-5-methyl-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.
