Trimethylarsine CAS 593-88-4 chemical structure

Description

As a certified reference material (CRM), Trimethylarsine 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.

Trimethylarsine (CAS 593-88-4) is a high-purity analytical reference standard with the molecular formula C3H9As and a molecular weight of 120.03 g/mol.

Based on its molecular formula C3H9As, Trimethylarsine contains an organic framework; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 120.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
