Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including MSOP.
MSOP (CAS 66515-29-5) is a high-purity analytical reference standard with the molecular formula C4H10NO6P and a molecular weight of 199.10 g/mol.
Owing to a carbohydrate-derived structure, an amide group, a phosphate ester group, MSOP is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 199.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), MSOP 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.
