Chemical Structure

1-Methylphosphinane-4-carboxylic acid 1-oxide CAS 945459-98-3 chemical structure

Description

1-Methylphosphinane-4-carboxylic acid 1-oxide (CAS 945459-98-3) is a high-purity analytical reference standard with the molecular formula C7H13O3P and a molecular weight of 176.15 g/mol.

The molecular framework of 1-Methylphosphinane-4-carboxylic acid 1-oxide (C7H13O3P) is characterized by a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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), 1-Methylphosphinane-4-carboxylic acid 1-oxide 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.
