Methyl 2-{1-[4-(phenylsulfanyl)phenyl]ethylidene}-1-hydrazinecarboxylate CAS 303148-78-9 chemical structure

Description

The occurrence of Methyl 2-{1-[4-(phenylsulfanyl)phenyl]ethylidene}-1-hydrazinecarboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Methyl 2-{1-[4-(phenylsulfanyl)phenyl]ethylidene}-1-hydrazinecarboxylate (CAS 303148-78-9), a certified reference material (molecular formula C16H16N2O2S, MW 300.38 g/mol) for analytical method development and quality control.

Structurally, Methyl 2-{1-[4-(phenylsulfanyl)phenyl]ethylidene}-1-hydrazinecarboxylate (C16H16N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 300.38 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
