Chemical Structure
Description
As a certified reference material (CRM), 2-Ethyl-4,5,6,7-tetrahydro-2H-indazole-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.
CATO supplies 2-Ethyl-4,5,6,7-tetrahydro-2H-indazole-3-carboxylic acid (CAS 32275-62-0), a certified reference material (molecular formula C10H14N2O2, MW 194.23 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-Ethyl-4,5,6,7-tetrahydro-2H-indazole-3-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
