Ambroxol hydrochloride | CAS 23828-92-4

The hydrochloride of a dibrominated trans-aminocyclohexanol active molecule, with relative stereochemistry, salt composition and related substances central to ambroxol material qualification.

CAS23828-92-4
Molecular formulaC13H19Br2ClN2O
Molecular weight414.56 g/mol

Product overview

Ambroxol hydrochloride links a dibrominated aminobenzyl group to a trans-substituted cyclohexanol ring through a secondary amine. The hydrochloride is a defined salt, distinct from ambroxol free base. Both the trans relationship on the cyclohexane ring and the chloride-containing composition belong in identity review. Grade selection should also clarify whether the material is for research, quantitative analysis or pharmaceutical manufacture.

Application context

Ambroxol is the active molecule in established expectorant medicines. Its hydrochloride also appears in research-reagent and pharmacopoeial reference-standard catalogues, supporting analytical method work and pharmaceutical development. For procurement, relate the chosen manufacturer and grade to the intended use: a quantitative standard needs an assigned value, while an API qualification programme needs the applicable specification and supporting batch documentation. Formulation properties are evaluated with the selected dosage form and excipients.

Chemistry and synthetic role

The molecule contains an aromatic amino group, a secondary benzylamine linkage and a cyclohexanol hydroxyl; the trans ring relationship and two bromine substituents distinguish its identity.

Quality review

Trans configuration

Request an identity and related-isomer method capable of addressing the specified cyclohexanol relationship.

Hydrochloride composition

Confirm chloride content and distinguish salt assay from free-base-equivalent expression.

Related brominated species

Agree chromatographic specificity for relevant process-related or degradation components, together with water and residual-solvent requirements.

Preparing a specification

State ambroxol hydrochloride, trans identity, required specification or research use, assay expression, chloride, water and related-substance criteria.

Packaging and storage

Confirm container compatibility, closure and net weight for the selected grade and destination. Follow the actual supplier SDS and batch label for storage and transport.

Documentation

Request the batch COA, SDS and analytical methods covering the agreed purchasing specification. Confirm which supporting chromatograms and application-specific records are available from the selected manufacturer.

Procurement questions

Is this ambroxol free base?

No. CAS 23828-92-4 identifies the hydrochloride.

Why specify trans configuration?

The relative arrangement on the cyclohexanol ring is part of ambroxol’s defined structure.

Does a research grade automatically meet a pharmacopoeial specification?

The proposed grade must be assessed against the named specification and its required tests.
