3-Ethyl-1-(2-hydroxyethyl)-1H-pyrazole-4-carboxylic acid CAS 1171994-87-8

Description

The occurrence of 3-Ethyl-1-(2-hydroxyethyl)-1H-pyrazole-4-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-Ethyl-1-(2-hydroxyethyl)-1H-pyrazole-4-carboxylic acid (CAS 1171994-87-8), a certified reference material (molecular formula C8H12N2O3, MW 184.19 g/mol) for analytical method development and quality control.

The molecular framework of 3-Ethyl-1-(2-hydroxyethyl)-1H-pyrazole-4-carboxylic acid (C8H12N2O3) is characterized by an amino-acid-derived structure, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

As a certified reference material (CRM), 3-Ethyl-1-(2-hydroxyethyl)-1H-pyrazole-4-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
