1-(1,1-Dioxidotetrahydrothiophen-3-yl)-4,5,6,7-tetrahydro-1h-indazole-3-carboxylic acid CAS 889941-08-6

Description

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.

1-(1,1-Dioxidotetrahydrothiophen-3-yl)-4,5,6,7-tetrahydro-1h-indazole-3-carboxylic acid (CAS 889941-08-6) is a high-purity analytical reference standard with the molecular formula C12H16N2O4S and a molecular weight of 284.33 g/mol.

1-(1,1-Dioxidotetrahydrothiophen-3-yl)-4,5,6,7-tetrahydro-1h-indazole-3-carboxylic acid (C12H16N2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
