rel-(3R,4R)-1-(tert-Butoxycarbonyl)-4-propylpyrrolidine-3-carboxylic acid CAS 2138012-25-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including rel-(3R,4R)-1-(tert-Butoxycarbonyl)-4-propylpyrrolidine-3-carboxylic acid.

rel-(3R,4R)-1-(tert-Butoxycarbonyl)-4-propylpyrrolidine-3-carboxylic acid (CAS 2138012-25-4), molecular formula C13H23NO4 and molecular weight 257.33 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, rel-(3R,4R)-1-(tert-Butoxycarbonyl)-4-propylpyrrolidine-3-carboxylic acid (C13H23NO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 257.33 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
