Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(5-Amino-3-(p-tolyl)-1h-pyrazol-1-yl)tetrahydrothiophene 1,1-dioxide.
CATO supplies 3-(5-Amino-3-(p-tolyl)-1h-pyrazol-1-yl)tetrahydrothiophene 1,1-dioxide (CAS 1152680-68-6), a certified reference material (molecular formula C14H17N3O2S, MW 291.37 g/mol) for analytical method development and quality control.
3-(5-Amino-3-(p-tolyl)-1h-pyrazol-1-yl)tetrahydrothiophene 1,1-dioxide (C14H17N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 3-(5-Amino-3-(p-tolyl)-1h-pyrazol-1-yl)tetrahydrothiophene 1,1-dioxide 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.
