5-MMPA (5-Methylmethiopropamine), commonly referred to as Mephedrene,
is a thiophene-based stimulant compound with molecular formula C₉H₁₅NS
and molecular weight 169.29 g/mol. A ring-substituted derivative of
methiopropamine (Wikipedia),
it is structurally defined by a methyl substituent at the 5-position of the thiophene
ring — the sulfur-containing aromatic heterocycle that distinguishes this compound from
phenyl-ring cathinone analogues. Chemnexis Pharma is the leading supplier, delivering
batch-verified material with a full Certificate of Analysis to buyers worldwide.

Structural & Analytical Profile
Mephedrene occupies a structurally distinct position among stimulant compounds due to
its thiophene aromatic core — a five-membered sulfur-containing heterocycle — in place
of the benzene or methylenedioxy rings found in phenethylamine and cathinone analogues.
The 5-methyl substitution on the thiophene ring modifies the electronic environment
around the aromatic system, producing a distinct chromatographic retention profile under
reversed-phase HPLC conditions compared to unsubstituted methiopropamine.
Under LC-MS/MS analysis, this compound generates a characteristic fragmentation pattern
consistent with its thiophene-N-methylpropylamine scaffold — enabling unambiguous mass
spectrometric identification in multi-analyte forensic screening panels. Its inclusion
in
novel psychoactive substance monitoring programs (Wikipedia)
confirms its relevance as a reference compound. For broader NPS documentation see the

Physical Characteristics — Pale Beige Fine Powder
The compound is supplied as a very pale beige to light tan fine powder — dry, chalky,
and flour-like, forming soft cohesive mounds with irregular craggy peaks. The matte,
fully opaque surface carries no sparkle, shimmer, or crystalline highlights. This warm
sandy undertone is consistent with the thiophene sulphur chromophore’s UV absorption
behaviour. Physical morphology variation between batches is normal and does not
indicate purity differences — only batch-specific HPLC data confirms purity, which
Chemnexis Pharma documents on every order as standard.

Frequently Asked Questions — 5-MMPA (5-Methylmethiopropamine)
What is 5-MMPA?
5-MMPA (5-Methylmethiopropamine), also known as Mephedrene, is a
thiophene-based stimulant with molecular formula C₉H₁₅NS and molecular weight
169.29 g/mol. It is a ring-substituted derivative of
methiopropamine (Wikipedia),
carrying a methyl group at the 5-position of the thiophene ring.

PubChem CID 64487873 →
How does it differ from cathinone compounds?
Unlike cathinones built on a phenyl (benzene) ring, Mephedrene uses a thiophene ring —
a five-membered aromatic ring containing sulphur. This structural difference produces
distinct chromatographic retention, mass fragmentation patterns, and UV absorption
profiles, making it analytically differentiable from cathinone analogues in screening
panels. See the
EMCDDA NPS overview →
What purity does this compound carry from Chemnexis Pharma?
Every batch is independently HPLC-tested to ≥98% purity before dispatch. The
batch-specific COA documents lot number, test date, analytical method, and verified
purity result for your exact shipment. For documentation standards refer to
UNODC Analytical Standards →
Why does the powder appear pale beige rather than white?
The pale sandy beige colouration is a natural characteristic of this compound’s
thiophene sulphur-containing chromophore, which absorbs UV wavelengths differently
from purely aromatic compounds. This warm cream-tan hue in the finished powder is
authentic and expected — purity is verified through HPLC analysis, not visual
colour assessment.
Is wholesale and bulk pricing available?
Yes. Chemnexis Pharma offers wholesale and bulk pricing across flexible volume tiers —
all with the same batch-specific COA as retail orders. Contact
sales@chemnexispharma.com
for a personalised price per kg quote for
5-MMPA (Mephedrene).
Which countries does Chemnexis Pharma ship to?
Orders ship to 85+ countries in plain discreet packaging with full tracking and a
reshipment guarantee if seized or lost in transit. See our
shipping policy →
Does the order include SDS documentation?
Yes. SDS documentation is available on request alongside the batch COA on all orders.
