Chemical Structure
Description
2-(3-Iodobicyclo[1.1.1]pentan-1-yl)acetic acid (CAS 2209086-71-3), molecular formula C7H9IO2 and molecular weight 252.05 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(3-Iodobicyclo[1.1.1]pentan-1-yl)acetic acid (C7H9IO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. 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 252.05 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
