Chemical Structure
Description
Structurally, 4-(Chloromethyl)-5-methyl-2-(m-tolyl)oxazole (C12H12ClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 221.68 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
4-(Chloromethyl)-5-methyl-2-(m-tolyl)oxazole (CAS 521266-92-2) is a high-purity analytical reference standard with the molecular formula C12H12ClNO and a molecular weight of 221.68 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
