1,3-Dimethoxybenzene | CAS 151-10-0

The dimethyl ether of resorcinol provides a meta-dioxygenated aromatic scaffold for synthesis and aroma evaluation; its ring substitution, fully etherified oxygens and residual phenolic components define material qualification.

CAS151-10-0
Molecular formulaC8H10O2
Molecular weight138.16 g/mol

Product overview

The two methoxy groups are separated by one aromatic carbon. Both oxygens are methylated, so this structure differs from resorcinol and from partially methylated phenols. It is also the meta isomer of dimethoxybenzene, distinct from veratrole. Published applications include oxathiane spiroketal donor chemistry, where the electron-rich aromatic unit participates in an S-arylation strategy. The molecule also has an aroma-chemical context. Qualification should keep the structural isomer, residual phenols and intended grade explicit rather than relying on a shared molecular formula.

Application context

Research on oxathiane spiroketal donors has used 1,3-dimethoxybenzene in an umpolung S-arylation approach. This is a specialised synthetic application of its substituted aromatic ring. Aroma development represents a separate use requiring sensory evaluation and appropriate grade documentation. For either project, define the meta isomer unambiguously and establish a method that resolves other dimethoxybenzenes. Where relevant to the selected production route, include resorcinol and partially methylated phenols in the impurity discussion.

Chemistry and synthetic role

The 1,3-methoxy pattern places oxygen functions in a meta relationship; both are aryl methyl ethers.

Quality review

Confirm meta substitution

Use structure-sensitive identification and GC resolution of dimethoxybenzene isomers.

Review incomplete methylation

Assess resorcinol and methoxyphenol residues when relevant to manufacture.

Match the application grade

Define synthetic or aroma use and the evidence needed for that use.

Preparing a specification

Specify CAS 151-10-0, the meta isomer, analytical purity method, relevant phenolic residues and any water, colour or sensory criteria.

Packaging and storage

Packaging and net weight are agreed for the selected grade, order quantity and destination. Check the actual supplier SDS and label for storage and transport requirements.

Documentation

Request a batch COA, SDS and the analytical methods for the acceptance criteria below. Confirm which supporting chromatograms and identity data are available from the selected manufacturer.

Procurement questions

Is this veratrole?

No. Veratrole is the 1,2-isomer.

Does the molecule have free phenolic OH?

No; a free OH would indicate a different compound.

What should an aroma enquiry add?

Sensory acceptance criteria and the required grade documentation.
