Chemical Structure
Description
CATO supplies 1-(9H-Fluoren-2-yl)-2-phenylhydrazine (CAS 26319-86-8), a certified reference material (molecular formula C7H9N5O2, MW 195.18 g/mol) for analytical method development and quality control.
Structurally, 1-(9H-Fluoren-2-yl)-2-phenylhydrazine (C7H9N5O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 195.18 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
