Chemical Structure
Description
The occurrence of 3-Hydroxy-2-methylnaphthalene-1(4H)-thione is closely related to sulfur-containing functionality, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Hydroxy-2-methylnaphthalene-1(4H)-thione (CAS 6383-54-6), a certified reference material (molecular formula C11H10S, MW 174.26 g/mol) for analytical method development and quality control.
3-Hydroxy-2-methylnaphthalene-1(4H)-thione (C11H10S) contains sulfur-containing functionality, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
