Chemical Structure
Description
The occurrence of 1H-pyrrolo[3,2-h]quinoline-3-sulfonic acid is closely related to an amide group, a sulfone group, a carboxylic acid 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-sulfonic acid (CAS 2231234-17-4), molecular formula C11H20N2O3S and molecular weight 260.35 g/mol, is a CATO reference standard with documented purity and traceability.
1H-pyrrolo[3,2-h]quinoline-3-sulfonic acid (C11H20N2O3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-sulfonic 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.
