Diethyl (2-Thienylmethyl)phosphonate CAS 2026-42-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diethyl (2-Thienylmethyl)phosphonate.

Diethyl (2-Thienylmethyl)phosphonate (CAS 2026-42-8), molecular formula C9H15O3PS and molecular weight 234.25 g/mol, is a CATO reference standard with documented purity and traceability.

Diethyl (2-Thienylmethyl)phosphonate (C9H15O3PS) contains a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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), Diethyl (2-Thienylmethyl)phosphonate 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.
