Chemical Structure
Description
Structurally, p-Nitrophenylhydrazine sulfate (C6H7N3O2H2O4S) contains a carbohydrate-derived structure, an amide group, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 251.21 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies p-Nitrophenylhydrazine sulfate (CAS 58332-97-1), a certified reference material (molecular formula C6H7N3O2H2O4S, MW 251.21 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
