3-Chloro-2-phenyl-2H-pyrazolo[4,3-c]pyridine-7-carbaldehyde CAS 62176-73-2

Description

The occurrence of 3-Chloro-2-phenyl-2H-pyrazolo[4,3-c]pyridine-7-carbaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Chloro-2-phenyl-2H-pyrazolo[4,3-c]pyridine-7-carbaldehyde (CAS 62176-73-2) is a high-purity analytical reference standard with the molecular formula C13H8ClN3O and a molecular weight of 257.68 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Chloro-2-phenyl-2H-pyrazolo[4,3-c]pyridine-7-carbaldehyde is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 257.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 3-Chloro-2-phenyl-2H-pyrazolo[4,3-c]pyridine-7-carbaldehyde 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.
