Product Description
3-[(2-Aminoethyl)amino]propanesulfonic acid, CAS 14235-54-2, is an organic sulfur-containing compound with the molecular formula C₅H₁₄N₂O₃S and a molecular weight of approximately 182.24 g/mol. Its structure consists of a propanesulfonic acid chain linked to an aminoethylamino group.
The combination of amino and sulfonic acid functionality distinguishes this compound from simple alkanesulfonic acids and other amino-containing sulfur compounds. Correct identification is particularly important when comparing chemical listings, because some online catalogs incorrectly associate CAS 14235-54-2 with expandable polystyrene (EPS). EPS is a polymeric foam material and is not a synonym for this small-molecule compound.
This product may be evaluated for laboratory research, chemical investigation, or use as a synthesis intermediate where its specific structure is required. Its suitability for any particular reaction or formulation depends on the required purity, impurity limits, and process conditions. Specific applications should therefore be confirmed against technical documentation rather than inferred from unrelated product listings.
Before purchasing, confirm that the quotation, label, and Certificate of Analysis (COA) all identify CAS 14235-54-2 and the correct chemical name. Request the current Technical Data Sheet (TDS) and Safety Data Sheet (SDS), and verify assay, appearance, solubility, storage conditions, packaging, and available batch documentation. Do not rely on specifications or application claims published for EPS or other compounds with similar-looking catalog entries.

Product Applications
1. Chemical Research and Structural Investigation
The compound may be considered for research involving amino-containing sulfonic acids. Confirm identity and purity requirements before using it in analytical or experimental work.
2. Chemical Synthesis Intermediate Evaluation
Where a synthesis route specifically requires this molecular structure, the material may be evaluated as a potential intermediate. Compatibility, reaction behavior, and yield must be established for the individual synthesis rather than assumed from the chemical name alone.
3. Laboratory Method Development
Researchers may assess the compound in analytical method development or other laboratory investigations that require a defined amino-sulfonic acid structure. Suitability depends on the method, sample preparation, and impurity tolerance.
4. Specialty Chemical Development
For exploratory specialty-chemical projects, this compound may be screened when its functional groups and molecular structure align with the target design. Scale-up should proceed only after the intended reaction, quality requirements, and handling procedures have been validated.
The applications above describe potential evaluation areas, not confirmed commercial end uses for every grade. Confirm application suitability with the supplier and relevant technical data before production use.
