2-Isopropyl-N,2,3-trimethylbutyramide is a chemical name associated with Cooling Agent WS-23, identified by CAS No. 51115-67-4. This page is intended as a chemical identity and technical reference for buyers, R&D teams and quality personnel who need to verify WS-23 raw material information and supporting documentation.

WS-23 may appear under different chemical naming conventions in supplier documents, product specifications and technical databases. For material verification, the chemical name should be reviewed together with the CAS number, molecular information and batch-specific documentation.

1. What Is 2-Isopropyl-N,2,3-trimethylbutyramide?

2-Isopropyl-N,2,3-trimethylbutyramide is commonly referenced in the cooling ingredient industry as Cooling Agent WS-23. It belongs to the WS-series of synthetic cooling compounds and is supplied as a crystalline raw material for use in formulation development.

When purchasing or reviewing WS-23, buyers may search by the chemical name, CAS 51115-67-4, the common name WS-23, or one of its listed synonyms. Using several identifiers together helps avoid confusion between different cooling ingredients.

2. Chemical Identity and Synonyms

Product specifications should be confirmed against the current batch COA and applicable technical documentation.

3. WS-23 Naming and Identification

The same WS-23 material may be described using different chemical names or abbreviations. For this reason, the product name alone should not be used as the only identity check.

For routine purchasing and technical review, the following identifiers should be considered together:

• Common product name: Cooling Agent WS-23
• CAS number: 51115-67-4
• Chemical name: 2-Isopropyl-N,2,3-trimethylbutyramide
• Molecular formula: C10H21NO
• FEMA number: 3804
• JECFA number: 1595

4. Basic Physical Information

Commercial WS-23 is typically supplied as a white crystalline powder. The purity specification used on this product page is ≥99.0%. Actual analytical results may vary slightly by production batch and should therefore be reviewed using the corresponding Certificate of Analysis.

5. How to Verify WS-23 Raw Material

Before approving WS-23 for purchasing, quality review or formulation evaluation, the raw material identity should be checked against the supplier's batch documentation.

1. Confirm the CAS number. Check that the documentation identifies the material as CAS 51115-67-4.
2. Check the chemical name. Review whether the chemical name or recognized synonym corresponds to WS-23.
3. Review the batch COA. Confirm assay, appearance and other batch-specific test results.
4. Match the batch or lot number. The batch number on the COA should correspond to the supplied material.
5. Review the product specification. Compare the agreed product specification with the batch analytical results.
6. Check supporting technical documents. Review the SDS, TDS and other required documentation according to the intended use and destination market.

6. Technical Documentation

Technical documentation can be provided to support customer qualification, quality review and formulation assessment.
