Description

Compared with other compounds in its class, the molecular weight of 219.30 g/mol gives (2R,3R)-1-[(R)-tert-butylsulfinyl]-3-ethyl-aziridine-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(2R,3R)-1-[(R)-tert-butylsulfinyl]-3-ethyl-aziridine-2-carboxylic acid (CAS 2641826-59-5), molecular formula C9H17NO3S and molecular weight 219.30 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (2R,3R)-1-[(R)-tert-butylsulfinyl]-3-ethyl-aziridine-2-carboxylic acid (C9H17NO3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
