Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(1-Chloroethyl)-3-methyl-1,2,4-oxadiazole.
CATO supplies 5-(1-Chloroethyl)-3-methyl-1,2,4-oxadiazole (CAS 79867-19-9), a certified reference material (molecular formula C5H7ClN2O, MW 146.57 g/mol) for analytical method development and quality control.
5-(1-Chloroethyl)-3-methyl-1,2,4-oxadiazole (C5H7ClN2O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
CATO manufactures 5-(1-Chloroethyl)-3-methyl-1,2,4-oxadiazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
