Chemical Structure
Description
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.
4,5,6,7-Tetrahydro-1h-indazole-3-carbohydrazide (CAS 90434-92-7) is a high-purity analytical reference standard with the molecular formula C8H12N4O and a molecular weight of 180.21 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4,5,6,7-Tetrahydro-1h-indazole-3-carbohydrazide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 4,5,6,7-Tetrahydro-1h-indazole-3-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.
