1,2-Propanediol, polymer with 1,3-diisocyanatomethylbenzene and 1,1'-methylenebis[isocyanatobenzene] (CAS 153965-58-3), molecular formula C15H14N2O2C9H6N2O2C3H8O2 and molecular weight 504.54 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2-Propanediol, polymer with 1,3-diisocyanatomethylbenzene and 1,1'-methylenebis[isocyanatobenzene] (C15H14N2O2C9H6N2O2C3H8O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
