Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Oxepanone, polymer with 1,1'-methylenebis[isocyanatobenzene] and 2,2'-[1,4-phenylenebis(oxy)]bis[ethanol].
2-Oxepanone, polymer with 1,1'-methylenebis[isocyanatobenzene] and 2,2'-[1,4-phenylenebis(oxy)]bis[ethanol] (CAS 152187-62-7), molecular formula C15H14N2O2C10H14O4C6H10O2 and molecular weight 566.65 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Oxepanone, polymer with 1,1'-methylenebis[isocyanatobenzene] and 2,2'-[1,4-phenylenebis(oxy)]bis[ethanol] (C15H14N2O2C10H14O4C6H10O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 566.65 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
