Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-({5-[3-(trifluoromethoxy)benzamido]-1,3,4-thiadiazol-2-yl}sulfanyl)acetate.
CATO supplies Ethyl 2-({5-[3-(trifluoromethoxy)benzamido]-1,3,4-thiadiazol-2-yl}sulfanyl)acetate (CAS 329699-49-2), a certified reference material (molecular formula C14H12F3N3O4S2, MW 407.39 g/mol) for analytical method development and quality control.
Ethyl 2-({5-[3-(trifluoromethoxy)benzamido]-1,3,4-thiadiazol-2-yl}sulfanyl)acetate (C14H12F3N3O4S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Ethyl 2-({5-[3-(trifluoromethoxy)benzamido]-1,3,4-thiadiazol-2-yl}sulfanyl)acetate 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.
