Chemical Structure
Description
The occurrence of Efonidipine Hydrochloride Monoethanolate - API Standards is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Efonidipine Hydrochloride Monoethanolate - API Standards (CAS 111011-76-8), molecular formula C34H38N3O7PC2H6OHCl and molecular weight 714.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Efonidipine Hydrochloride Monoethanolate - API Standards (C34H38N3O7PC2H6OHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.5, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 714.19 g/mol, it falls into the 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.
CATO manufactures Efonidipine Hydrochloride Monoethanolate - API Standards under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
