Description

The occurrence of N-[(1S,2R)-1-Benzyl-2-hydroxy-2-((2R,4R)-4-propoxy-pyrrolidin-2-yl)-ethyl]-3-[(R)-2-(4-methyl-thiazol-2-yl)-pyrrolidine-1-carbonyl]-5-oxazol-2-yl-benzamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-[(1S,2R)-1-Benzyl-2-hydroxy-2-((2R,4R)-4-propoxy-pyrrolidin-2-yl)-ethyl]-3-[(R)-2-(4-methyl-thiazol-2-yl)-pyrrolidine-1-carbonyl]-5-oxazol-2-yl-benzamide (CAS 1221263-92-8), molecular formula C35H41N5O5S and molecular weight 643.80 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-[(1S,2R)-1-Benzyl-2-hydroxy-2-((2R,4R)-4-propoxy-pyrrolidin-2-yl)-ethyl]-3-[(R)-2-(4-methyl-thiazol-2-yl)-pyrrolidine-1-carbonyl]-5-oxazol-2-yl-benzamide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 643.80 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
