Chemical Structure
Description
The occurrence of Ethyl 5-amino-1-(2-(methylsulfonyl)phenyl)-1H-pyrazole-3-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ethyl 5-amino-1-(2-(methylsulfonyl)phenyl)-1H-pyrazole-3-carboxylate (CAS 1427021-62-2), a certified reference material (molecular formula C13H15N3O4S, MW 309.34 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 5-amino-1-(2-(methylsulfonyl)phenyl)-1H-pyrazole-3-carboxylate (C13H15N3O4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Ethyl 5-amino-1-(2-(methylsulfonyl)phenyl)-1H-pyrazole-3-carboxylate 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.
