Chemical Structure
Description
The occurrence of 5-Hexyl-2-styryloxazole-4-carboxylic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Hexyl-2-styryloxazole-4-carboxylic acid (CAS 89724-24-3), molecular formula C18H21NO3 and molecular weight 299.36 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Hexyl-2-styryloxazole-4-carboxylic acid (C18H21NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 299.36 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-Hexyl-2-styryloxazole-4-carboxylic acid 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.
