4-(4-Aminophenyl)morpholin-3-one | CAS 438056-69-0

An aniline-bearing morpholinone fragment documented in rivaroxaban preparation, combining a para amino group with an N-aryl lactam whose identity, related substances and assay basis deserve separate attention during material qualification.

CAS438056-69-0
Molecular formulaC10H12N2O2

Product overview

A free para amino group and an N-aryl morpholin-3-one ring define this rivaroxaban building block. The lactam carbonyl is an essential part of the retained ring fragment. Evaluate aromatic-stage impurities alongside identity, and specify the separate roles of chromatographic purity and quantitative assay in accepting a batch.

Chemical identity

Chemical name
4-(4-Aminophenyl)morpholin-3-one
CAS number
438056-69-0
Molecular formula
C10H12N2O2

Application context

Rivaroxaban process literature uses this aminophenyl morpholinone as a defined intermediate, including work on a solid form for downstream synthesis. The para amino group provides the assembly site and the morpholinone ring supplies the retained lactam fragment. Specify the required form and assess aromatic related substances, chemical assay and chromatographic purity for the receiving process.

Chemistry and synthetic role

A para aromatic primary amine and an N-aryl morpholin-3-one ring coexist in this achiral building block. The amino group provides the site for subsequent assembly, while the ring carbonyl remains part of the morpholinone fragment.

Quality review

Confirm the lactam carbonyl

Use a structural identity test that distinguishes the morpholinone from an aryl morpholine or a different ring-carbonyl isomer.

Review the aromatic amino stage

Review method separation of relevant nitro, protected-amino and other aromatic compounds associated with the selected route.

Separate assay methods

Specify the role of chromatographic purity and any independent titrimetric assay, including their calculation and acceptance criteria.

Preparing a specification

State the exact morpholin-3-one structure, required identity test, chromatographic purity and any independent assay criterion. Define relevant aromatic related substances with the proposed manufacturer. If the receiving process requires moisture or exposure controls, include those requirements explicitly rather than inferring them from a general pharmaceutical-intermediate grade.

Packaging and storage

Agree packaging, net weight and transport arrangements for the selected grade, quantity and destination. Confirm storage and handling conditions using the current SDS for the proposed material.

Documentation

Request a proposed specification, batch COA, current SDS and structure-identification data. Confirm the chromatographic method and the calculation basis of any titrimetric assay, and agree handling requirements with the selected supplier.

Procurement questions

Is this an ordinary phenylmorpholine?

No. The morpholin-3-one carbonyl and para amino group are essential to its identity.

Which aromatic-stage compounds should be reviewed?

Relevant nitro, protected-amino or other aromatic species identified for the chosen manufacturing route.

Can titration replace the impurity chromatogram?

It cannot establish chromatographic separation of related substances. Agree the role of each test.
