N'-(5-Nitro-1-benzothiophene-2-carbonyl)thiophene-2-carbohydrazide CAS 477847-41-9

Description

N'-(5-Nitro-1-benzothiophene-2-carbonyl)thiophene-2-carbohydrazide (C14H9N3O4S2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

N'-(5-Nitro-1-benzothiophene-2-carbonyl)thiophene-2-carbohydrazide (CAS 477847-41-9), molecular formula C14H9N3O4S2 and molecular weight 347.37 g/mol, is a CATO reference standard with documented purity and traceability.

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.
