Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 199.98 g/mol gives 3-Iodopropionic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Iodopropionic Acid (CAS 141-76-4), a certified reference material (molecular formula C3H5IO2, MW 199.98 g/mol) for analytical method development and quality control.
Structurally, 3-Iodopropionic Acid (C3H5IO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 199.98 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.
CATO manufactures 3-Iodopropionic Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
