Chemical Structure

tert-Butyl (R)-oxirane-2-carboxylate CAS 2165950-95-6 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 (R)-oxirane-2-carboxylate.

tert-Butyl (R)-oxirane-2-carboxylate (CAS 2165950-95-6), molecular formula C7H12O3 and molecular weight 144.17 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, tert-Butyl (R)-oxirane-2-carboxylate (C7H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 144.17 g/mol, it falls into the low-molecular-weight range.

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.
