Chemical Structure

Diallate CAS 2303-16-4 chemical structure

Description

Diallate (CAS 2303-16-4), molecular formula C10H17Cl2NOS and molecular weight 270.22 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Diallate (C10H17Cl2NOS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Diallate 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.
