Chemical Structure

Tert-butyl ((1R,2S)-2-(o-tolyl)cyclopropyl)carbamate CAS 1859949-36-2 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 Tert-butyl ((1R,2S)-2-(o-tolyl)cyclopropyl)carbamate.

Tert-butyl ((1R,2S)-2-(o-tolyl)cyclopropyl)carbamate (CAS 1859949-36-2), molecular formula C15H21NO2 and molecular weight 247.33 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Tert-butyl ((1R,2S)-2-(o-tolyl)cyclopropyl)carbamate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

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.
