CAS 115-18-4 Methylbutenol for Specialty Chemical Intermediate Applications

Starting With the Right Chemical Identity

When sourcing a specialty chemical internationally, one of the most useful lessons is to confirm the material identity before comparing price, packaging, or delivery terms. Methylbutenol CAS 115-18-4, also known as 2-methylbut-3-en-2-ol, is a good example of why this step matters. Different commercial and technical documents may use alternative names, so the CAS number provides a consistent reference when communicating with suppliers.

Methylbutenol has the molecular formula C5H10O and a molecular weight of 86.13 g/mol. It is also known as 2-methyl-3-buten-2-ol and dimethylvinylcarbinol. For international purchasing teams, keeping these identifiers together makes it easier to align supplier quotations, technical documents, internal specifications, and downstream manufacturing requirements.

How Methylbutenol Fits Chemical Intermediate Sourcing

The practical value of a Methylbutenol chemical intermediate comes from its molecular structure and its place in downstream chemical processes. The molecule contains an alcohol group together with an unsaturated carbon-carbon bond, giving it characteristics relevant to organic chemistry and specialty chemical applications.

From a sourcing perspective, it is useful to begin with the intended application rather than treating every inquiry as a generic raw material purchase. A laboratory, fragrance producer, chemical manufacturer, or distributor may have different requirements for purity, documentation, packaging, and quantity. Defining these requirements early can make supplier communication considerably more efficient.

Physical Properties and Handling Considerations

Methylbutenol is described as a clear, colorless to slightly yellow liquid. Reported physical data include a melting point of approximately -43°C and a boiling point around 98–99°C. Its density is approximately 0.824 g/mL at 25°C, while reported vapor pressure is about 51 mm Hg at 25°C.

These properties are useful when considering storage, transportation, and process conditions. Since the material is flammable, handling should be based on the supplier's latest SDS and applicable local transportation and workplace requirements. Container compatibility, ventilation, temperature control, and ignition-source management should all be considered before industrial use.

Applications of 2-Methyl-3-Buten-2-Ol

Methylbutenol has documented relevance in flavor and fragrance applications, while cosmetic references associate the substance with perfuming functions. Its suitability for a particular manufacturing route, however, depends on the customer's formulation or synthesis requirements and the required quality standard.

This is why describing Methylbutenol simply as a chemical raw material can be insufficient. Its commercial role may vary according to the downstream process, and technical teams need to evaluate purity, compatibility, regulatory requirements, and processing conditions together.

What to Look for in a Methylbutenol Supplier

For overseas companies searching for a Methylbutenol supplier in China, supplier evaluation normally goes beyond product availability. Consistent product identification, clear technical documentation, responsive communication, and the ability to support export requirements can all influence the purchasing process.

Zhejiang Kingvolt lists Methylbutenol within its chemical product portfolio and provides product information for international customers. When evaluating supply, buyers can request current specifications, SDS documentation, packaging details, available quantities, lead time, and shipping arrangements to establish whether the material fits their procurement requirements.

A Practical Approach to International Procurement

In our experience, a clear inquiry often produces a clearer quotation. Instead of sending only “Methylbutenol,” it is more effective to include CAS 115-18-4, required quantity, destination, intended application, quality expectations, and documentation requirements. This reduces the possibility of misunderstandings caused by different chemical naming conventions.

The same approach becomes even more valuable when a material will be purchased repeatedly. Establishing a consistent product specification from the first order creates a reference for future procurement and makes it easier to compare subsequent batches.

For companies looking for a CAS 115-18-4 chemical intermediate, accurate identification should therefore be the starting point, followed by technical qualification, commercial evaluation, logistics planning, and ongoing supply communication. Zhejiang Kingvolt can provide a starting point for overseas customers evaluating Methylbutenol for their chemical sourcing needs.
