Chemical Structure
Description
As a certified reference material (CRM), Methyl 4-{4-[(3,4-dichlorophenyl)methoxy]-5-methyl-1,3-thiazol-2-yl}benzoate 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.
Methyl 4-{4-[(3,4-dichlorophenyl)methoxy]-5-methyl-1,3-thiazol-2-yl}benzoate (CAS 338409-56-6) is a high-purity analytical reference standard with the molecular formula C19H15Cl2NO3S and a molecular weight of 408.30 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Methyl 4-{4-[(3,4-dichlorophenyl)methoxy]-5-methyl-1,3-thiazol-2-yl}benzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.30 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.
