Chemical Structure

tert-Butylchloro(methyl)phosphine CAS 25196-13-8 chemical structure

Description

The molecular framework of tert-Butylchloro(methyl)phosphine (C5H12ClP) is characterized by organophosphorus functionality, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies tert-Butylchloro(methyl)phosphine (CAS 25196-13-8), a certified reference material (molecular formula C5H12ClP, MW 138.58 g/mol) for analytical method development and quality control.

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), tert-Butylchloro(methyl)phosphine 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.
