Chemical Structure

ARSINE CAS 7784-42-1 chemical structure

Description

The occurrence of ARSINE is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

ARSINE (CAS 7784-42-1) is a high-purity analytical reference standard with the molecular formula H3As and a molecular weight of 77.95 g/mol.

The molecular framework of ARSINE (H3As) is characterized by an inorganic composition. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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), ARSINE 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.
