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 1-Methyl-3-(3-(triethoxysilyl)propyl)-1H-imidazol-3-ium chloride.
1-Methyl-3-(3-(triethoxysilyl)propyl)-1H-imidazol-3-ium chloride (CAS 338741-79-0), molecular formula C13H27N2O3SiCl and molecular weight 322.91 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Methyl-3-(3-(triethoxysilyl)propyl)-1H-imidazol-3-ium chloride (C13H27N2O3SiCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 322.91 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
