Is 2-Phenylethylamine Hydrochloride the same material as phenethylamine free base?

No. CAS 156-28-5 identifies the hydrochloride salt, while phenethylamine free base is a different material with a different molecular-weight basis. Specify the salt form and whether assay is reported as the hydrochloride or free-base equivalent before comparing specifications or calculating process charge.

What information is needed to match a 2-Phenylethylamine Hydrochloride grade?

State the intended manufacturing use and required assay method, identity test, appearance, water, related amines, residual solvents and any application-specific impurity limits. The requested quantity, packing, shelf-life expectation and document set should accompany the specification so the offered grade and batch COA can be reviewed correctly.

2-Phenylethylamine Hydrochloride CAS 156-28-5

2-Phenylethylamine Hydrochloride, also called phenethylamine hydrochloride or PEA HCl, CAS 156-28-5, EC 205-849-2, is the hydrochloride salt of phenethylamine with molecular formula C₈H₁₂ClN and molecular weight 157.64 g/mol. It must be distinguished from phenethylamine free base, CAS 64-04-0. Supply is intended for qualified research or synthesis where salt identity, assay, water, free base, related amines, residual solvents and destination-market compliance have been reviewed; a CAS match does not establish pharmaceutical or human-use suitability.

Identity and physicochemical profile

Item	Technical guidance
Correct identity	2-Phenylethylamine hydrochloride; phenethylammonium chloride
CAS / EC	156-28-5 / 205-849-2
Formula / molecular weight	C₈H₁₂ClN / 157.64 g/mol
Salt boundary	The hydrochloride salt is distinct from phenethylamine free base, CAS 64-04-0
Key purchase controls	Identity, assay basis, water, free base, related amines, residual solvents, chloride or salt stoichiometry and physical form
Regulatory boundary	Synthesis-grade identity does not establish compendial status, medicinal approval or permission for every destination and end use

Applications and grade selection

2-Phenylethylamine Hydrochloride may be evaluated as a salt-form intermediate or analytical material in authorized organic synthesis and research. The selected form should match the buyer’s reaction, solubility, assay method and regulatory file; free-base data should not be transferred automatically.

Confirm whether the hydrochloride salt or phenethylamine free base is required.
Set limits for water, free base, related amines, residual solvents and salt stoichiometry.
Review end-user, destination, import and documentation requirements before quotation.

Storage and handling

Keep tightly closed and protected from moisture and incompatible acids, bases or oxidizers under the current COA and SDS. Use controlled access and sampling where site or destination rules require it.

Safety, documentation and procurement

Use suitable containment, gloves, eye protection and dust control. Procurement requires exact salt form, intended use, specification, quantity, packaging, destination and any end-use or compliance documentation.
