2-Amino-5-cyano-N,3-dimethylbenzamide | CAS 890707-29-6

A cyanoanthranilamide component in published cyantraniliprole routes, this molecule combines a free aromatic amino group with an N-methyl amide, making substitution pattern and related halo precursors important qualification targets.

CAS890707-29-6
Molecular formulaC10H11N3O
Molecular weight189.21 g/mol

Product overview

The two methyl groups in this name occupy different environments: one is attached to the amide nitrogen and the other to the aromatic ring. Together with the 2-amino and 5-cyano substituents, they define the anthranilamide fragment used in published cyantraniliprole chemistry. The free aromatic amino group provides a connection site while the pre-existing N-methyl amide remains part of the required fragment. The corresponding 5-chloro or 5-bromo compounds are separate identities and should not be treated as alternative names. For procurement, a generic benzamide purity statement is consequently too broad. Structural confirmation and a route-informed related-substance profile provide more useful evidence, with residual-metal review added where the selected manufacturing process justifies it.

Application context

Cyantraniliprole routes couple this anthranilamide with a brominated chloropyridyl-pyrazole carboxylic-acid component. It supplies the cyano-substituted aromatic amide portion; the free aromatic amino group forms the next connection. Preparations through halo-substituted precursors make precursor separation a useful qualification target. Discuss related-substance methods and residual metals where appropriate to the selected manufacturing route.

Chemistry and synthetic role

The ortho amino group is chemically distinct from the N-methyl carboxamide. Acylation of the aromatic amino function builds the second amide connection while retaining the ring cyano substituent.

Quality review

Verify cyano versus halo substitution

Confirm the 5-cyano structure; a 5-chloro analogue belongs to different downstream chemistry.

Confirm the N-methyl amide

Identity evidence should distinguish ring methyl substitution and amide N-methylation rather than treating dimethyl as ambiguous.

Trace process-related carryover

Agree precursor limits and metal screening only where warranted by the selected route; request suitable chromatographic separation.

Preparing a specification

Specify the 2-amino/5-cyano/N,3-dimethyl structure, assay and HPLC method, route-relevant halo precursor limits and any justified residual-metal criteria. Define water or solvent corrections for quantitative content.

Packaging and storage

Confirm packaging format, net weight and transport arrangements for the selected grade, order quantity and destination. Request the applicable SDS and label to establish storage and handling conditions.

Documentation

Request the proposed specification, batch COA and current SDS. Confirm availability of the identity data and analytical methods relevant to the checks above; documents depend on the selected manufacturer and grade.

Procurement questions

Is the 5-chloro analogue interchangeable?

No. Replacing cyano by chlorine changes the intermediate and its downstream identity.

Which nitrogen forms the new amide?

The free aromatic amino group is the connection site in the cited anthranilamide route.

When should residual metals be included in the specification?

Review catalysts and reagents used by the selected manufacturer, then set relevant elemental limits, methods and reporting levels for the receiving process.
