Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 493.00 g/mol gives N-1-Ethoxyethyl Losartan Carboxaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-1-Ethoxyethyl Losartan Carboxaldehyde (CAS 165276-40-4), molecular formula C26H29ClN6O2 and molecular weight 493.00 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N-1-Ethoxyethyl Losartan Carboxaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 493.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), N-1-Ethoxyethyl Losartan Carboxaldehyde 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.
