Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Amino-4-bromo-1h-pyrazol-1-yl)-N-ethyl-N-methylacetamide.
CATO supplies 2-(3-Amino-4-bromo-1h-pyrazol-1-yl)-N-ethyl-N-methylacetamide (CAS 1248441-76-0), a certified reference material (molecular formula C8H13BrN4O, MW 261.12 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-Amino-4-bromo-1h-pyrazol-1-yl)-N-ethyl-N-methylacetamide (C8H13BrN4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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.
As a certified reference material (CRM), 2-(3-Amino-4-bromo-1h-pyrazol-1-yl)-N-ethyl-N-methylacetamide 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.
