Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including rel-2-Methyl-3-((7R,11S,E)-3,7,11,15-tetramethylhexadec-2-en-1-yl)naphthalene-1,4-dione.
rel-2-Methyl-3-((7R,11S,E)-3,7,11,15-tetramethylhexadec-2-en-1-yl)naphthalene-1,4-dione (CAS 79082-97-6), molecular formula C31H46O2 and molecular weight 450.70 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, rel-2-Methyl-3-((7R,11S,E)-3,7,11,15-tetramethylhexadec-2-en-1-yl)naphthalene-1,4-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 450.70 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.
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.
