Chemical Structure
Description
As a certified reference material (CRM), 7-Chloro-1H-pyrrolo[3,2-b]pyridine-2-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.
7-Chloro-1H-pyrrolo[3,2-b]pyridine-2-carbaldehyde (CAS 1427503-64-7) is a high-purity analytical reference standard with the molecular formula C8H5ClN2O and a molecular weight of 180.59 g/mol.
7-Chloro-1H-pyrrolo[3,2-b]pyridine-2-carbaldehyde (C8H5ClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
