Chemical Structure

二氧化碳-<SUP>18</SUP>O<SUB>2</SUB> CAS 2537-69-1 chemical structure

Description

二氧化碳-<SUP>18</SUP>O<SUB>2</SUB> (CAS 2537-69-1), molecular formula C[18O]2 and molecular weight 48.01 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C[18O]2, 二氧化碳-<SUP>18</SUP>O<SUB>2</SUB> contains a hydroxyl group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 48.01 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
