Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 300.43 g/mol gives 1,3-Benzenediol, polymer with ethenyltriethoxysilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3-Benzenediol, polymer with ethenyltriethoxysilane (CAS 68239-98-5), molecular formula C8H18O3SiC6H6O2 and molecular weight 300.43 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,3-Benzenediol, polymer with ethenyltriethoxysilane (C8H18O3SiC6H6O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 300.43 g/mol, it falls into the moderately-high-molecular-weight range. 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.
