Chemical Structure

Dimethrin CAS 70-38-2 chemical structure

Description

CATO supplies Dimethrin (CAS 70-38-2), a certified reference material (molecular formula C19H26O2, MW 286.41 g/mol) for analytical method development and quality control.

Based on its molecular formula C19H26O2, Dimethrin contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 286.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Dimethrin 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.
