3,5-Bis((2-oxopropyl)thio)isothiazole-4-carbonitrile CAS 24134-81-4

Description

As a certified reference material (CRM), 3,5-Bis((2-oxopropyl)thio)isothiazole-4-carbonitrile 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.

3,5-Bis((2-oxopropyl)thio)isothiazole-4-carbonitrile (CAS 24134-81-4), molecular formula C10H10N2O2S3 and molecular weight 286.39 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,5-Bis((2-oxopropyl)thio)isothiazole-4-carbonitrile (C10H10N2O2S3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 286.39 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
