Chemical Structure
Description
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 supplies 1H-Pyrazolo[3,4-c]pyridine-3-carboxylic acid tert-butyl ester (CAS 2387535-14-8), a certified reference material (molecular formula C11H13N3O2, MW 219.24 g/mol) for analytical method development and quality control.
Structurally, 1H-Pyrazolo[3,4-c]pyridine-3-carboxylic acid tert-butyl ester (C11H13N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 219.24 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 1H-Pyrazolo[3,4-c]pyridine-3-carboxylic acid tert-butyl ester 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.
