Buy 4B-MAR powder (4‑bromomethamphetamine) is a halogenated methamphetamine derivative belonging to the phenethylamine and amphetamine chemical classes.
It is researched primarily for its role in toxicological screening, metabolite analysis, and SAR (structure‑activity relationship) modeling of halogenated stimulants.

Organic / Inorganic Chemistry

Property	Specification
IUPAC Name	N‑methyl‑1‑(4‑bromophenyl)propan‑2‑amine
Formula	C₁₀H₁₄BrN
Molecular Weight	228.13 g · mol⁻¹
Functional Groups	Secondary amine, aromatic bromo substituent, aliphatic chain
Chemical Family	Arylalkylamine / halogenated amphetamines
Physical Form	Crystalline powder (HCl salt form commonly used in research)
Melting Point (HCl)	≈ 186–188 °C
Solubility	Soluble in ethanol and methanol; sparingly in water.
Reactivity	Stable to air/light under dry conditions; decomposes under strong acidic hydrolysis.

Chemical Biology

Mechanism: Indirect monoamine releasing agent affecting dopamine and norepinephrine transporters.
SAR note: Bromine substitution at the para position increases lipophilicity and DAT binding affinity compared with amphetamines lacking halogen substitution.
Metabolism: N‑demethylation → 4‑bromoamphetamine → oxidation to 4‑bromobenzoic acid derivatives.
Toxicology: Neurotoxic in cellular models via oxidative stress and dopaminergic axon damage.
Applications: Used under licence for LC‑MS and GC‑MS tox library calibration and comparative metabolite profiling.

Computational Chemistry

Parameter	Prediction (B3LYP/6‑31G*)
Dipole Moment	2.85 Debye
HOMO–LUMO Gap	≈ 5.05 eV
Predicted log P	2.9 – 3.1
pKa (amine)	9.7
TPSA	27 Å²
Rotatable Bonds	3
Docking energy (hDAT)	≈ –9.2 kcal · mol⁻¹
Interpretation: Heavier halogen substitution increases binding interaction and membrane affinity relative to 4F‑MAR.

Environmental Chemistry

Hydrolysis: Very slow under neutral pH; amine hydrochloride salt stable for weeks.
Photodecomposition: Yield of 4‑bromobenzaldehyde and amine fragments under UV exposure.
Soil/Water Fate: Moderate sorption on organic matter; low biodegradability.
Persistence: Moderate (half‑life weeks to months in aerobic conditions).
Environmental risk: Potential bioaccumulation (log Kow ≈ 3.0); incineration recommended for disposal.
Disposal method: Licensed high‑temperature incineration (> 1100 °C).
