Chemical Structure
Description
The occurrence of 4,7-Methano-1H-inden-6-ol, 3a,4,5,6,7,7a-hexahydro-, polymer with 1,3-diisocyanatomethylbenzene and .alpha.,.alpha.,4-trimethyl-3-cyclohexene-1-methanol is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,7-Methano-1H-inden-6-ol, 3a,4,5,6,7,7a-hexahydro-, polymer with 1,3-diisocyanatomethylbenzene and .alpha.,.alpha.,4-trimethyl-3-cyclohexene-1-methanol (CAS 68334-89-4) is a high-purity analytical reference standard with the molecular formula C9H6N2O2C10H18OC10H14O and a molecular weight of 478.63 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4,7-Methano-1H-inden-6-ol, 3a,4,5,6,7,7a-hexahydro-, polymer with 1,3-diisocyanatomethylbenzene and .alpha.,.alpha.,4-trimethyl-3-cyclohexene-1-methanol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 478.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
