1-(1-(2-Methoxyethyl)-2,5-dimethyl-1H-pyrrol-3-yl)-2-((5-methyl-1,3,4-thiadiazol-2-yl)thio)ethan-1-one CAS 690642-71-8 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 1-(1-(2-Methoxyethyl)-2,5-dimethyl-1H-pyrrol-3-yl)-2-((5-methyl-1,3,4-thiadiazol-2-yl)thio)ethan-1-one.

CATO supplies 1-(1-(2-Methoxyethyl)-2,5-dimethyl-1H-pyrrol-3-yl)-2-((5-methyl-1,3,4-thiadiazol-2-yl)thio)ethan-1-one (CAS 690642-71-8), a certified reference material (molecular formula C14H19N3O2S2, MW 325.45 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-(1-(2-Methoxyethyl)-2,5-dimethyl-1H-pyrrol-3-yl)-2-((5-methyl-1,3,4-thiadiazol-2-yl)thio)ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 325.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 1-(1-(2-Methoxyethyl)-2,5-dimethyl-1H-pyrrol-3-yl)-2-((5-methyl-1,3,4-thiadiazol-2-yl)thio)ethan-1-one 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.
