Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 122.55 g/mol gives Chloromethyl propionate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Chloromethyl propionate (CAS 5402-53-9), molecular formula C4H7ClO2 and molecular weight 122.55 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4H7ClO2, Chloromethyl propionate contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 122.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
