Indolin-5-yldimethylphosphine oxide CAS 145159-59-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Indolin-5-yldimethylphosphine oxide.

Indolin-5-yldimethylphosphine oxide (CAS 145159-59-7) is a high-purity analytical reference standard with the molecular formula C10H14NOP and a molecular weight of 195.20 g/mol.

Indolin-5-yldimethylphosphine oxide (C10H14NOP) contains a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
