2-Oxo-4-(p-tolylthio)-2H-chromene-3-carbaldehyde CAS 330472-43-0

Description

Compared with other compounds in its class, the molecular weight of 296.34 g/mol gives 2-Oxo-4-(p-tolylthio)-2H-chromene-3-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Oxo-4-(p-tolylthio)-2H-chromene-3-carbaldehyde (CAS 330472-43-0), molecular formula C17H12O3S and molecular weight 296.34 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, 2-Oxo-4-(p-tolylthio)-2H-chromene-3-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 2-Oxo-4-(p-tolylthio)-2H-chromene-3-carbaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
