Is methyl n-amyl ether the same material as 1-Methoxypentane?

Yes. Methyl n-amyl ether and pentyl methyl ether are established names for 1-Methoxypentane, CAS 628-80-8. Do not rely on the shorter term amyl ether, which can be used ambiguously around other pentyl ether structures. Confirm the CAS number and an agreed GC identity method.

1-Methoxypentane CAS 628-80-8

1-Methoxypentane (CAS 628-80-8), also called Methyl pentyl ether or Methyl n-amyl ether, is a low-polarity aliphatic ether used as a reaction solvent, extraction medium or formulation solvent. Confirm GC purity, water, distillation range, acidity, nonvolatile residue and peroxide status against the current COA and SDS.

CAS: 628-80-8
Synonyms: 1-Methoxypentane, Methyl pentyl ether, Pentyl methyl ether, Methyl n-amyl ether
Molecular Formula: C₆H₁₄O
Grade: Specified by identity, GC purity, water, distillation range, acidity, nonvolatile residue and peroxide status; see the current COA.
Package: Confirm approved container, inerting or stabilizer needs, fill quantity, temperature controls and dangerous-goods requirements against the SDS.

Identity and physicochemical profile

Item	Technical guidance
Product identity	1-Methoxypentane; methyl pentyl ether
CAS number	628-80-8
Formula / molecular weight	C₆H₁₄O / 102.18 g/mol
Chemical character	Low-polarity aliphatic ether requiring flammability and peroxide-risk assessment
Key purchase controls	Identity, GC purity, water, distillation range, acidity, nonvolatile residue and peroxide status
Selection boundary	Environmental, fuel and process-replacement claims require application-specific evidence

Applications and grade selection

1-Methoxypentane may be screened as a reaction solvent, extraction medium or formulation solvent when its polarity, boiling behavior, material compatibility and safety profile fit the process.

Set limits for GC purity, water, acidity, distillation range, residue and peroxide condition using agreed methods.
Evaluate solvency, reaction selectivity, extraction efficiency, recovery and impurity carryover at process-relevant scale.
Review flash-point controls, equipment compatibility, vapor management and waste treatment before substitution.

Storage and handling

Store in tightly closed compatible containers away from heat, ignition sources, oxidizers and prolonged air or light exposure. Apply the supplier’s current peroxide-management, retest and inhibitor guidance.

Safety, documentation and procurement

Treat 1-Methoxypentane as a flammable ether and use bonding, grounding, ventilation and suitable personal protection according to the current SDS. Procurement should include grade, methods, quantity, package, destination and dangerous-goods requirements.
