3,3-Dichloro-1-(4-nitrophenyl)piperidin-2-one | CAS 881386-01-2

A gem-dichlorinated lactam appearing in published apixaban intermediate chemistry, where the two chlorines at C3 and the retained para nitro group distinguish the starting stage from subsequent substituted unsaturated compounds.

CAS881386-01-2
Molecular formulaC11H10Cl2N2O3
Molecular weight289.11 g/mol

Product overview

Both chlorine atoms occupy C3 of the same piperidin-2-one ring carbon. This gem-dichloro pattern, the saturated lactam and the N-linked para-nitrophenyl group define the intermediate. Match the required chlorination stage and review analytical separation from other chlorination states or subsequent substitution products relevant to the selected route.

Application context

A published apixaban route uses this gem-dichlorinated lactam before substitution involving a piperazine derivative. The two chlorines at C3 define its place among the lactam intermediates. Match the chlorination stage to the receiving reaction and assess separation from relevant unchlorinated, differently chlorinated or subsequent substitution products.

Chemistry and synthetic role

This saturated cyclic amide carries two chlorine atoms on C3, adjacent to the carbonyl, and a para-nitrophenyl group on the lactam nitrogen. The gem-dichloro centre defines the substrate used before subsequent substitution in the reported apixaban intermediate sequence.

Quality review

Locate both chlorine atoms

Confirm substitution at C3 on the same ring carbon; total chlorine content cannot establish connectivity.

Review chlorination-stage impurities

Discuss unchlorinated or differently chlorinated related compounds only in relation to the actual production route and method resolution.

Keep the nitro identity explicit

Identify the aromatic nitro stage separately from any corresponding amine or downstream aromatic substitution product.

Preparing a specification

Request the gem-dichloro piperidin-2-one under its exact CAS. Define structural identification, chromatographic purity and the supplier-specific related-compound panel. If different chlorination stages are relevant, agree their separation and reporting individually instead of relying on a single total assay.

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

Ask for a representative identity record and chromatographic method capable of distinguishing relevant chlorination states. Request the proposed limits, batch COA and current SDS; confirm any additional process-related data needed for the receiving route.

Procurement questions

Are the chlorines on the phenyl ring?

No. Both chlorine substituents are on C3 of the piperidinone ring.

Is the ring already morpholino-substituted?

No. This CAS identifies the saturated gem-dichloro lactam.

Which chlorination states should be considered in qualification?

The required gem-dichloro compound and any unchlorinated or differently chlorinated species relevant to the actual route and method.
