Chemical Structure
Description
Ramipril Benzyl Ester-d5 (CAS 1356929-60-6), molecular formula C30H33D5N2O5 and molecular weight 511.66 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, Ramipril Benzyl Ester-d5 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 511.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
