6-APB (Benzofury) is 1-(1-benzofuran-6-yl)propan-2-amine. The content below is written for a research-chemical category page covering 6-APB materials. It does not include dosing, administration, or human-use claims. Each product requires its own lot-specific COA confirming identity, salt form, and assay.

Introduction

6-APB is 1-(1-benzofuran-6-yl)propan-2-amine. It is a benzofuran derivative with an aminopropyl chain attached at the 6-position of the benzofuran ring. It is a positional isomer of 5-APB, which has the chain at the 5-position. It is sometimes informally called Benzofury. Products in this category are for laboratory research only where legally authorized. They are not medicines and are not sold for human consumption.

The free base is C₁₁H₁₃NO, 175.23 g·mol⁻¹, CAS 286834-85-3. The hydrochloride is C₁₁H₁₃NO·HCl, 211.69 g·mol⁻¹, CAS 286834-84-2. Products must state the free base or named salt on the label and COA. A category name does not confirm the identity or salt form of any individual lot.

Key Features & Benefits

• Defined 6-substituted benzofuran. The 6-position attachment is the structural marker that distinguishes it from 5-APB.
• Documented identity: free-base CAS 286834-85-3, formula C₁₁H₁₃NO.
• Distinct from 5-APB. That isomer has the chain at the 5-position (free-base CAS 286834-81-9).
• Suitable for controlled laboratory and forensic analytical work when legally authorized. Not for formulation or human administration.

Specifications Table

Applications in Research

Appropriate uses are non-clinical, institutionally approved, and legally authorized:

• Analytical reference material for HPLC, LC-MS, and NMR identification of 6-APB against a certified standard.
• Forensic differentiation from 5-APB and other benzofurans.
• Comparison of free-base versus hydrochloride lots.
• In vitro monoamine transporter assays where the protocol specifically covers this compound.

Do not describe or imply oral, insufflation, injection, or any other human route of administration. Do not treat any labeled milligram quantity as a dose.

Purity & Testing

A defensible product claim rests on the batch certificate of analysis for the specific form.

• HPLC for chromatographic purity, with retention that separates 6-APB from 5-APB.
• ¹H NMR confirming the 6-substituted benzofuran aromatic pattern and the aminopropyl chain.
• Mass spectrometry consistent with the free-base molecular ion of C₁₁H₁₃NO.
• Explicit statement of free base or named salt.
• Residual solvent and related-substance limits if stated by the supplier.

Store the COA with the lot number. Do not use a 5-APB CAS number for a 6-APB lot.

Disclaimer

For laboratory research use only, where legally authorized. Not for human or veterinary consumption, not for diagnostic or therapeutic use, and not a food, drug, or cosmetic. 6-APB is a Class B substance in the United Kingdom and Anlage II in Germany. Related benzofurans are controlled in many jurisdictions, and analogue rules may apply. Unauthorized possession, manufacture, distribution, or importation can be a criminal offense. Buyers are solely responsible for confirming legality, licensing, import rules, and institutional approval before ordering or handling any specific product. Handle under applicable controlled-substance and hazardous-chemical rules and dispose of waste according to local regulations. No statement on this page is a claim of safety, efficacy, or fitness for any human application. The category name does not replace lot-specific identity and purity data on the COA.

Frequently Asked Questions

What is 6-APB?
It is 1-(1-benzofuran-6-yl)propan-2-amine. The free base is C₁₁H₁₃NO, 175.23 g·mol⁻¹.

Is this the same as 5-APB?
No. 5-APB has the aminopropyl chain at the 5-position (CAS 286834-81-9). 6-APB has it at the 6-position, CAS 286834-85-3. Chromatographic and NMR methods distinguish the positional isomers.

What is Benzofury?
Benzofury is an informal name sometimes used for 6-APB or related benzofurans. Identity must be confirmed on the COA.

Which CAS number applies?
Free base CAS 286834-85-3. Hydrochloride CAS 286834-84-2. Confirm identity and salt form on the COA.

What purity is supplied?
Only the value stated on the specific lot COA, together with the analytical method. The method should resolve 6-APB from related isomers.

How should it be stored?
Sealed, cool, dry, and protected from light under the rules that apply. Keep the lot number with the COA.

Can it be used in humans?
No. It is not an approved medicine and is not sold for consumption. In the United Kingdom it is Class B. Check local law before purchase or handling.

What analytical methods confirm identity?
HPLC with isomer resolution, NMR for the 6-substituted pattern, and mass spectrometry consistent with C₁₁H₁₃NO. The COA should state free base or salt.
