Chemical Structure

MOPS half sodium salt CAS 117961-20-3 chemical structure

Description

As a certified reference material (CRM), MOPS half sodium salt 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.

MOPS half sodium salt (CAS 117961-20-3), molecular formula C7H15NO4SC7H14NO4SNa and molecular weight 440.50 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H15NO4SC7H14NO4SNa, MOPS half sodium salt contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 440.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
