Is hydroquinone benzyl methyl ether a synonym for 4-Benzyloxyanisole?

Yes, when the name refers to the para-substituted structure identified by CAS 6630-18-8. It does not make other benzyloxyanisole positional isomers equivalent. When matching material, confirm the full name, CAS number, structure and an agreed chromatographic or spectral identity method.

4-Benzyloxyanisole (Hydroquinone Benzyl Methyl Ether) CAS 6630-18-8

4-Benzyloxyanisole (CAS 6630-18-8), also called Hydroquinone benzyl methyl ether or 1-Benzyloxy-4-methoxybenzene, is a para-substituted aromatic diether used as a protected aromatic building block in organic synthesis. Confirm identity, assay, positional isomers, residual benzylating materials, deprotected phenols and residual solvents against the current COA and SDS.

Identity and physicochemical profile

Item	Technical guidance
Correct identity	4-Benzyloxyanisole; hydroquinone benzyl methyl ether
CAS / EC or List no.	6630-18-8 / 654-563-8
Formula / molecular weight	C₁₄H₁₄O₂ / 214.26 g/mol
Structural character	Para-substituted aromatic diether containing benzyloxy and methoxy groups
Key purchase controls	Identity, assay, positional isomers, residual benzylating materials, deprotected phenols, residual solvents and physical form
Use boundary	It is not hydroquinone or MEHQ and should not be assigned inhibitor performance from the synonym alone

Applications and grade selection

4-Benzyloxyanisole may be evaluated as a protected aromatic building block in controlled organic synthesis, including routes that use benzyl protection followed by selective transformation or deprotection.

Confirm para substitution and distinguish positional isomers using appropriate spectroscopic and chromatographic methods.
Set limits for assay, deprotected phenols, residual benzylating reagents, solvents and route-specific impurities.
Qualify reaction conversion, selectivity, deprotection behavior and final-product impurity carryover at small scale.

Storage and handling

Store in the original sealed container under the light, temperature and moisture conditions stated in the current documentation. Prevent contamination and follow the supplier’s guidance for sampling, resealing and retest period.

Safety, documentation and procurement

Handle with suitable gloves, eye protection and ventilation according to the current SDS. A procurement inquiry should state the target specification, intended reaction, sample or project quantity, packaging, destination and document requirements.
