Chemical Structure
Description
Structurally, 5-Chloro-3-[3-(trifluoromethyl)phenyl]-1,2-oxazole-4-carbaldehyde (C11H5ClF3NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 275.61 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.
5-Chloro-3-[3-(trifluoromethyl)phenyl]-1,2-oxazole-4-carbaldehyde (CAS 1188136-36-8) is a high-purity analytical reference standard with the molecular formula C11H5ClF3NO2 and a molecular weight of 275.61 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.
As a certified reference material (CRM), 5-Chloro-3-[3-(trifluoromethyl)phenyl]-1,2-oxazole-4-carbaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
