Chemical Structure

(1R,2R)-Cyclopropane-1,2-dicarboxylic acid CAS 34202-45-4 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 (1R,2R)-Cyclopropane-1,2-dicarboxylic acid.

CATO supplies (1R,2R)-Cyclopropane-1,2-dicarboxylic acid (CAS 34202-45-4), a certified reference material (molecular formula C5H6O4, MW 130.10 g/mol) for analytical method development and quality control.

Structurally, (1R,2R)-Cyclopropane-1,2-dicarboxylic acid (C5H6O4) contains a carbohydrate-derived structure. 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 130.10 g/mol, it falls into the low-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).

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.
