Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 36288-25-2 1-[2-(4-Methylphenyl)ethenyl]naphthalene DTXSID70733651.
36288-25-2 1-[2-(4-Methylphenyl)ethenyl]naphthalene DTXSID70733651 (CAS 36288-25-2), molecular formula C19H16 and molecular weight 244.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a polycyclic aromatic system, 36288-25-2 1-[2-(4-Methylphenyl)ethenyl]naphthalene DTXSID70733651 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 244.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
