1-(1,1-Dioxidotetrahydrothiophen-3-yl)-3-methyl-1H-pyrazolo[3,4-b]pyridine-5-carbaldehyde CAS 1235440-51-3

Description

The occurrence of 1-(1,1-Dioxidotetrahydrothiophen-3-yl)-3-methyl-1H-pyrazolo[3,4-b]pyridine-5-carbaldehyde 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 1-(1,1-Dioxidotetrahydrothiophen-3-yl)-3-methyl-1H-pyrazolo[3,4-b]pyridine-5-carbaldehyde (CAS 1235440-51-3), a certified reference material (molecular formula C12H13N3O3S, MW 279.31 g/mol) for analytical method development and quality control.

The molecular framework of 1-(1,1-Dioxidotetrahydrothiophen-3-yl)-3-methyl-1H-pyrazolo[3,4-b]pyridine-5-carbaldehyde (C12H13N3O3S) 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 1-(1,1-Dioxidotetrahydrothiophen-3-yl)-3-methyl-1H-pyrazolo[3,4-b]pyridine-5-carbaldehyde 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.
