10-Bromodecanoic acid | CAS 50530-12-6

An omega-brominated C10 acid offering a terminal alkyl bromide and a carboxyl group for long-chain molecule construction, with both end groups important to qualification.

CAS50530-12-6
Molecular formulaC10H19BrO2
Molecular weight251.16 g/mol

Product overview

10-Bromodecanoic acid places a primary bromide at the end opposite its carboxylic acid group. The structure Br(CH2)9COOH contains ten carbons in total, including the carboxyl carbon. These different termini make it a useful chain-length-defined building block. Identity review should distinguish it from shorter or longer omega-bromo acids, from positional isomers and from esterified forms that change the acid-end chemistry.

Application context

Published materials research uses 10-bromodecanoic acid in preparation of long-chain bisphosphonate molecules investigated for control of calcium-carbonate crystallization. In such synthesis, the chain provides separation between functional regions while the bromide and carboxyl termini enable further transformations. Its role is a precursor in the construction of the designed molecule. Qualification should confirm both terminal functions and the chain length before relating a batch to the desired surface- or mineral-interaction study.

Chemistry and synthetic role

A primary alkyl bromide and a carboxylic acid sit at opposite ends of a nine-methylene segment, enabling differentiated end-group chemistry.

Quality review

Chain-length identity

Use structural data and a suitable separation method to distinguish C10 acid from neighboring homologues.

Terminal bromide integrity

Review related terminally substituted or unbrominated material that could change coupling performance.

Free-acid content

Combine acid assay with chromatographic purity; confirm ester content and water if relevant to activation at the acid end.

Preparing a specification

State the free C10 omega-bromo acid, chromatographic purity, acid-content basis, terminal-group related substances and any water requirement for the intended coupling.

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

Does the C10 count include the carboxyl carbon?

Yes. The chain contains nine methylene groups plus one carboxyl carbon.

Is ethyl 10-bromodecanoate the same input?

It retains the terminal bromide but masks the acid as an ester and has a different identity.

Can acid titration confirm the bromide end?

No. A structural or chromatographic test is also needed.
