Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Oxo-2,3-Dihydro-1H-Indene-4-Carbothioamide.
1-Oxo-2,3-Dihydro-1H-Indene-4-Carbothioamide (CAS 138764-18-8) is a high-purity analytical reference standard with the molecular formula C10H9NOS and a molecular weight of 191.25 g/mol.
The molecular framework of 1-Oxo-2,3-Dihydro-1H-Indene-4-Carbothioamide (C10H9NOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
