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 Ethyl 2-((2-(tert-butyl)-2,6-dihydro-4H-thieno[3,4-c]pyrazol-3-yl)amino)-2-oxoacetate.
CATO supplies Ethyl 2-((2-(tert-butyl)-2,6-dihydro-4H-thieno[3,4-c]pyrazol-3-yl)amino)-2-oxoacetate (CAS 1105189-85-2), a certified reference material (molecular formula C13H19N3O3S, MW 297.37 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 2-((2-(tert-butyl)-2,6-dihydro-4H-thieno[3,4-c]pyrazol-3-yl)amino)-2-oxoacetate (C13H19N3O3S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Ethyl 2-((2-(tert-butyl)-2,6-dihydro-4H-thieno[3,4-c]pyrazol-3-yl)amino)-2-oxoacetate 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.
