Chemical Structure
Description
As a certified reference material (CRM), 4H-furo[3,2-b]pyrrole-5-carbohydrazide 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.
4H-furo[3,2-b]pyrrole-5-carbohydrazide (CAS 91206-29-0), molecular formula C7H7N3O2 and molecular weight 165.15 g/mol, is a CATO reference standard with documented purity and traceability.
4H-furo[3,2-b]pyrrole-5-carbohydrazide (C7H7N3O2) contains an amino-acid-derived structure, an amide 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
