Chemical Structure

5-(5-(2,6-Dichloro-4-(4,5-dihydrooxazol-2-yl)phenoxy)pentyl)-3-methylisoxazole CAS 107355-45-3 chemical structure

Description

5-(5-(2,6-Dichloro-4-(4,5-dihydrooxazol-2-yl)phenoxy)pentyl)-3-methylisoxazole (CAS 107355-45-3) is a high-purity analytical reference standard with the molecular formula C18H20Cl2N2O3 and a molecular weight of 383.27 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-(5-(2,6-Dichloro-4-(4,5-dihydrooxazol-2-yl)phenoxy)pentyl)-3-methylisoxazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 383.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

As a certified reference material (CRM), 5-(5-(2,6-Dichloro-4-(4,5-dihydrooxazol-2-yl)phenoxy)pentyl)-3-methylisoxazole 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.
