2-(5-Amino-3-ethyl-4-(methylsulfonyl)-1H-pyrazol-1-yl)ethanol CAS 1708436-67-2 chemical structure

Description

The occurrence of 2-(5-Amino-3-ethyl-4-(methylsulfonyl)-1H-pyrazol-1-yl)ethanol is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(5-Amino-3-ethyl-4-(methylsulfonyl)-1H-pyrazol-1-yl)ethanol (CAS 1708436-67-2), molecular formula C8H15N3O3S and molecular weight 233.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(5-Amino-3-ethyl-4-(methylsulfonyl)-1H-pyrazol-1-yl)ethanol (C8H15N3O3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 2-(5-Amino-3-ethyl-4-(methylsulfonyl)-1H-pyrazol-1-yl)ethanol 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.
