Compared with other compounds in its class, the molecular weight of 258.34 g/mol gives Chryseno[4,5-bcd]thiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Chryseno[4,5-bcd]thiophene (CAS 72076-98-3), a certified reference material (molecular formula C18H10S, MW 258.34 g/mol) for analytical method development and quality control.
Chryseno[4,5-bcd]thiophene (C18H10S) contains sulfur-containing functionality, a polycyclic aromatic 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 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.
