Product Selection
C12 Acyl Requirement
Dodecanoyl Chloride is suitable when a synthesis route requires a straight-chain twelve-carbon acyl group.
Direct Acylation
The acid chloride group provides a direct reaction site for introducing the dodecanoyl group into suitable organic substrates.
Liquid Processing
The material is a liquid at 20°C, allowing controlled charging and transfer in process systems selected for the chemical and operating conditions.
Key Product Advantages
Defined Chain Length
The straight C12 chain provides a consistent long-chain acyl component where chain length forms part of the required molecular structure.
Direct Reactive Group
The acid chloride functionality provides a defined site for acylation reactions involving suitable alcohols, amines, and related reactive substrates.
Clear Chemical Identification
CAS No. 112-16-3, molecular formula C₁₂H₂₃ClO, and molecular weight 218.76 g/mol provide consistent identifiers for specification review, documentation, and material control.
Application Areas
Organic Synthesis
Used as an acylating intermediate when a dodecanoyl group is required in the target molecule.
Long-Chain Functionalization
Used in synthesis routes where a linear C12 chain is introduced into an intermediate or finished chemical structure.
Surface Modification
Applicable to selected chemical modification processes requiring a long-chain acyl component.
Specialty Chemical Intermediates
Used in synthesis programs requiring a defined linear aliphatic acyl chloride for downstream processing.
Process Considerations
Moisture Control
Keep water and atmospheric moisture controlled during storage, sampling, transfer, and processing to maintain material integrity.
Temperature Management
The reported melting point is approximately -17°C. Processing temperature should be established according to the application, equipment configuration, and applicable product documentation.
Contact Materials
Process vessels, seals, piping, and transfer components should be selected for compatibility with acid chlorides and the intended operating conditions.
Quality Control
Purity Testing
GC purity provides a direct measurement of the main organic component. A reference commercial specification lists a minimum GC purity of 98.0%.
Physical Testing
Appearance, density, and refractive index provide supporting parameters for material identification and batch consistency.
Batch Verification
Each batch should be evaluated against the agreed specification before release for its intended application.
Documentation
Product Specification
The specification should define critical quality parameters, analytical methods, and acceptance limits applicable to the intended use.
Certificate of Analysis
A batch-specific COA records measured results for the supplied lot and supports incoming material verification.
Safety Data
SDS documentation provides information for handling, storage, transportation, and process-safety assessment.
Storage and Handling
Moisture Protection
Keep containers tightly closed and control exposure to atmospheric moisture during storage and routine handling.
Temperature Control
Store according to the applicable product specification and SDS. A cool, dark storage environment is commonly specified for this material.
Controlled Transfer
Use closed or controlled transfer procedures where required by the process design and site operating requirements.
Procurement Information
Specification
Confirm CAS No. 112-16-3, required purity, analytical method, appearance requirements, and other critical quality parameters before order placement.
Documentation
Confirm the required COA, SDS, product specification, batch identification, and destination-market documentation.
Application Fit
For recurring production requirements, provide the intended application, target purity, estimated annual volume, packaging requirement, and critical quality limits when requesting a quotation.
