Ethyl 1,2,2,3,3-pentadeuteriocyclopropane-1-carboxylate CAS 1794783-51-9

Description

The occurrence of Ethyl 1,2,2,3,3-pentadeuteriocyclopropane-1-carboxylate is closely related to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 1,2,2,3,3-pentadeuteriocyclopropane-1-carboxylate (CAS 1794783-51-9), molecular formula C6H5D5O2 and molecular weight 119.17 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Ethyl 1,2,2,3,3-pentadeuteriocyclopropane-1-carboxylate (C6H5D5O2) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 119.17 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
