1-Ethyl-4-ethynyl-1H-pyrazole CAS 573982-81-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Ethyl-4-ethynyl-1H-pyrazole.

CATO supplies 1-Ethyl-4-ethynyl-1H-pyrazole (CAS 573982-81-7), a certified reference material (molecular formula C7H8N2, MW 120.15 g/mol) for analytical method development and quality control.

Structurally, 1-Ethyl-4-ethynyl-1H-pyrazole (C7H8N2) contains a nitrile group, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 120.15 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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-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.
