Chemical Structure
Description
The occurrence of 1H-pyrrolo[3,2-h]quinoline-3-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1H-pyrrolo[3,2-h]quinoline-3-carboxylic acid (CAS 67509-88-0) is a high-purity analytical reference standard with the molecular formula C12H8N2O2 and a molecular weight of 212.20 g/mol.
Structurally, 1H-pyrrolo[3,2-h]quinoline-3-carboxylic acid (C12H8N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 212.20 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).
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), 1H-pyrrolo[3,2-h]quinoline-3-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.
