Chemical Structure

1-Ethyl-1H-pyrazol-5-ol hydrochloride CAS 106903-47-3 chemical structure

Description

CATO supplies 1-Ethyl-1H-pyrazol-5-ol hydrochloride (CAS 106903-47-3), a certified reference material (molecular formula C5H8N2OHCl, MW 148.59 g/mol) for analytical method development and quality control.

The molecular framework of 1-Ethyl-1H-pyrazol-5-ol hydrochloride (C5H8N2OHCl) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 1-Ethyl-1H-pyrazol-5-ol hydrochloride 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.
