Chemical Structure
Description
The occurrence of Quinapril Bicyclic Acid Benzyl Ester is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Quinapril Bicyclic Acid Benzyl Ester (CAS 103733-30-8), a certified reference material (molecular formula C17H17NO2HCl, MW 303.79 g/mol) for analytical method development and quality control.
Based on its molecular formula C17H17NO2HCl, Quinapril Bicyclic Acid Benzyl Ester contains a steroid 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 303.79 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Quinapril Bicyclic Acid Benzyl Ester 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.
