Chemical Structure
Description
As a certified reference material (CRM), Trimethobenzamide hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Trimethobenzamide hydrochloride (CAS 554-92-7), molecular formula C21H28N2O5HCl and molecular weight 424.92 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H28N2O5HCl, Trimethobenzamide hydrochloride contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 424.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
