Chemical Structure
Description
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.
p-Nitrobenzyl-(5R,6S)-2-(diphenylphosphoryloxy)-6-((1R)-1-hydroxyethyl)carbapen-2-em-3-carboxylate (CAS 75321-08-3) is a high-purity analytical reference standard with the molecular formula C28H25N2O10P and a molecular weight of 580.48 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, p-Nitrobenzyl-(5R,6S)-2-(diphenylphosphoryloxy)-6-((1R)-1-hydroxyethyl)carbapen-2-em-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 580.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
