Is Allyl Methyl Ether interchangeable with other C4H8O unsaturated ethers?

No. Allyl Methyl Ether has the connectivity CH2=CHCH2–O–CH3 and is identified by CAS 627-40-7. Other C4H8O ethers, including vinyl ethyl ether, have different structures and may behave differently. Confirm the full name, CAS number, structure and an agreed GC or spectral identity method when matching material.

Which controls should be stated in an Allyl Methyl Ether purchase specification?

Define GC assay, identity confirmation, appearance, water, relevant volatile impurities, stabilizer or peroxide status where applicable, and the required storage condition. Its low boiling point and high flammability also make container closure, headspace, temperature during handling and dangerous-goods documentation important parts of packaging and logistics qualification.

Allyl Methyl Ether CAS 627-40-7

Allyl Methyl Ether , CAS 627-40-7 and EC 210-997-6 , is the unsaturated ether 3-methoxyprop-1-ene . Its molecular formula is C4H8O and molecular weight is 72.11 g/mol. It is a volatile, flammable synthesis intermediate containing both an allyl group and an ether function. Buyers should define GC purity, water, peroxide status, stabilizer or inhibitor status, distillation profile and transport requirements for the actual grade rather than assume a universal formulation or shelf life.

CAS: 627-40-7
Synonyms: Allyl Methyl Ether, Methyl allyl ether, 3-Methoxyprop-1-ene, 3-Methoxypropene, 1-Propene 3-methoxy-
Einecs: 210-997-6
Molecular Formula: C₄H₈O
Grade: Confirm GC purity, water, peroxide status, inhibitor or stabilizer identity and level, distillation profile and reactive impurities against the current COA and SDS; qualify the intended reaction before use.
Package: State quantity and destination; confirm the current compatible sealed container, headspace or inerting requirements, closure, net fill, temperature controls and dangerous-goods requirements against the SDS.

Identity and physicochemical profile

Item	Technical guidance
Product identity	Allyl methyl ether; 3-methoxyprop-1-ene
CAS / EC	627-40-7 / 210-997-6
Formula / molecular weight	C₄H₈O / 72.11 g/mol
Chemical character	Volatile unsaturated ether requiring flammability, peroxide and stabilizer assessment
Key purchase controls	Identity, GC purity, water, peroxide status, inhibitor or stabilizer, distillation range, acidity and residual precursors
Application boundary	Polymerization or derivatization suitability depends on the stabilizer package and the buyer’s actual reaction conditions

Applications and grade selection

Allyl Methyl Ether may be used as an allylating or unsaturated building block in controlled addition, functionalization and polymer-related research. Its value depends on purity, inhibitor status, water and reaction selectivity. Buyers should also determine whether stabilizer removal or peroxide testing is required before processing.

State the required GC purity, water, peroxide limit and stabilizer identity or absence.
Evaluate reaction conversion, selectivity, inhibitor effects and volatile-loss control in the intended equipment.
Confirm compatible packaging, headspace, transport classification and temperature conditions before shipment.

Storage and handling

Store tightly closed in a qualified flammable-liquid container away from heat, ignition sources, oxidizers and prolonged air or light exposure. Follow the current SDS for bonding, grounding, peroxide testing, inhibitor management and retest timing.

Safety, documentation and procurement

Use closed transfer, effective ventilation and suitable personal protection. Do not distill aged ether material to dryness without an approved peroxide assessment. Procurement should define specification, quantity, package, destination and dangerous-goods documents.
