Chemical Structure
Description
CATO supplies 1-Isobutyl-6-methyl-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid (CAS 934062-78-9), a certified reference material (molecular formula C12H15N3O2, MW 233.27 g/mol) for analytical method development and quality control.
The molecular framework of 1-Isobutyl-6-methyl-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid (C12H15N3O2) is characterized by an amino-acid-derived structure, an amide 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.
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), 1-Isobutyl-6-methyl-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid 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.
