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

No. The hydrochloride salt uses CAS 156-28-5 and formula C8H12ClN, while phenethylamine free base uses CAS 64-04-0. Identity, molecular weight and process behavior differ.

Which tests should be specified for 2-Phenylethylamine Hydrochloride?

Include identity, assay basis, water, free phenethylamine, related amines, residual solvents and appearance. If chloride or salt stoichiometry is critical, state the required method and limit.

Can 2-Phenylethylamine Hydrochloride be quoted for regulated use?

CAS identity alone does not establish pharmaceutical grade. Provide the required standard, traceability, quality-system and destination-market documents, then request written confirmation that the offered grade and documents meet them.

How should Phenethylamine Hydrochloride and the free base be compared on an assay basis?

Compare them on a molar or corrected phenethylamine basis, not equal mass. The hydrochloride counterion changes formula weight, pH, handling and solubility, so confirm salt stoichiometry, water and assay basis before substituting one form for the other.

2-Phenylethylamine Hydrochloride CAS 156-28-5

2-Phenylethylamine Hydrochloride , CAS 156-28-5 and EC 205-849-2 , is the hydrochloride salt of phenethylamine. Its molecular formula is C8H12ClN and molecular weight is 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.
