Chemical Structure

1,3-Propanediol, 2-ethyl-2-(hydroxymethyl)-, polymer with .alpha.-hydro-.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] and 1,1'-methylenebis[4-isocyanatobenzene] CAS 9020-84-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 384.43 g/mol gives 1,3-Propanediol, 2-ethyl-2-(hydroxymethyl)-, polymer with .alpha.-hydro-.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] and 1,1'-methylenebis[4-isocyanatobenzene] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,3-Propanediol, 2-ethyl-2-(hydroxymethyl)-, polymer with .alpha.-hydro-.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] and 1,1'-methylenebis[4-isocyanatobenzene] (CAS 9020-84-2), molecular formula C15H10N2O2C6H14O3 and molecular weight 384.43 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 1,3-Propanediol, 2-ethyl-2-(hydroxymethyl)-, polymer with .alpha.-hydro-.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] and 1,1'-methylenebis[4-isocyanatobenzene] is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 384.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
