Description

CATO supplies 2-({5-[3-(diethylsulfamoyl)phenyl]-4-(1-methoxypropan-2-yl)-4h-1,2,4-triazol-3-yl}sulfanyl)acetic acid (CAS 745791-53-1), a certified reference material (molecular formula C18H26N4O5S2, MW 442.55 g/mol) for analytical method development and quality control.

2-({5-[3-(diethylsulfamoyl)phenyl]-4-(1-methoxypropan-2-yl)-4h-1,2,4-triazol-3-yl}sulfanyl)acetic acid (C18H26N4O5S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 2-({5-[3-(diethylsulfamoyl)phenyl]-4-(1-methoxypropan-2-yl)-4h-1,2,4-triazol-3-yl}sulfanyl)acetic 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.
