(5-Methoxy-2-methylphenyl)thiourea CAS 1022320-88-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5-Methoxy-2-methylphenyl)thiourea.

(5-Methoxy-2-methylphenyl)thiourea (CAS 1022320-88-2), molecular formula C9H12N2OS and molecular weight 196.27 g/mol, is a CATO reference standard with documented purity and traceability.

(5-Methoxy-2-methylphenyl)thiourea (C9H12N2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.
