Chemical Structure

1'-Phenyl-3,4-dihydro-2H-spiro[naphthalene-1,3'-[1,2,4]triazolidin]-5'-one CAS 131365-81-6 chemical structure

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.

CATO supplies 1'-Phenyl-3,4-dihydro-2H-spiro[naphthalene-1,3'-[1,2,4]triazolidin]-5'-one (CAS 131365-81-6), a certified reference material (molecular formula C17H17N3O, MW 279.34 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1'-Phenyl-3,4-dihydro-2H-spiro[naphthalene-1,3'-[1,2,4]triazolidin]-5'-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 279.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
