Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 3-(5-Amino-3-(furan-2-yl)-1H-pyrazol-1-yl)tetrahydrothiophene 1,1-dioxide (CAS 956329-25-2), a certified reference material (molecular formula C11H13N3O3S, MW 267.30 g/mol) for analytical method development and quality control.
The molecular framework of 3-(5-Amino-3-(furan-2-yl)-1H-pyrazol-1-yl)tetrahydrothiophene 1,1-dioxide (C11H13N3O3S) 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.
