4-(1-Ethyl-6-hydroxy-1H-indazol-3-yl)benzene-1,3-diol CAS 680610-92-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(1-Ethyl-6-hydroxy-1H-indazol-3-yl)benzene-1,3-diol.

4-(1-Ethyl-6-hydroxy-1H-indazol-3-yl)benzene-1,3-diol (CAS 680610-92-8), molecular formula C15H14N2O3 and molecular weight 270.28 g/mol, is a CATO reference standard with documented purity and traceability.

4-(1-Ethyl-6-hydroxy-1H-indazol-3-yl)benzene-1,3-diol (C15H14N2O3) contains a nitrogen-containing heterocyclic scaffold, 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
