Chemical Structure

ortho-Hydroxy Atorvastatin-d5 Calcium Salt CAS 265989-47-7 chemical structure

Description

The occurrence of ortho-Hydroxy Atorvastatin-d5 Calcium Salt is closely related to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

ortho-Hydroxy Atorvastatin-d5 Calcium Salt (CAS 265989-47-7), molecular formula C33H29D5FN2O6Ca and molecular weight 618.75 g/mol, is a CATO reference standard with documented purity and traceability.

ortho-Hydroxy Atorvastatin-d5 Calcium Salt (C33H29D5FN2O6Ca) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), ortho-Hydroxy Atorvastatin-d5 Calcium Salt 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.
