4-MPD (4-Methylpentedrone), also known as
4-methyl-α-methylamino-valerophenone, is a synthetic stimulant cathinone with
molecular formula C₁₃H₁₉NO and molecular weight
205.3 g/mol. A higher homolog of
mephedrone (4-MMC, Wikipedia)
and the p-methyl derivative of pentedrone, this compound is defined by a
para-methyl phenyl ring and a longer pentyl backbone chain compared to its
lower homologues. Chemnexis Pharma is the leading supplier, delivering
batch-verified material with a full Certificate of Analysis to buyers worldwide.

Structural & Analytical Profile
4-MPD occupies a well-defined structural position within the
methylpentedrone series. Its para-methyl phenyl ring is shared with mephedrone,
but the elongated pentyl backbone — one carbon longer than mephedrone and two
carbons longer than 4-MMC — produces a measurably higher lipophilicity and a
distinct reversed-phase HPLC retention time. This chain length difference is
analytically significant in multi-analyte cathinone screening panels where
homologue separation is required.
As documented on
Wikipedia: 4-Methylpentedrone,
the compound was originally synthesised in 1960, making it one of the earlier
entries in the cathinone homologue series. Cayman Chemical lists it as an
analytical reference material at ≥98% purity
— the benchmark Chemnexis Pharma meets or exceeds on every batch. For NPS

Frequently Asked Questions — 4-MPD (4-Methylpentedrone)
What is 4-MPD (4-Methylpentedrone)?
4-MPD (4-Methylpentedrone) is a synthetic cathinone stimulant with
molecular formula C₁₃H₁₉NO and molecular weight 205.3 g/mol. It is a higher homolog
of mephedrone and the p-methyl derivative of pentedrone, characterised by a
para-methyl phenyl ring and elongated pentyl backbone chain. CAS: 1373918-61-6.
Compound context:
Wikipedia: 4-Methylpentedrone →
How does 4-MPD differ from mephedrone (4-MMC)?
Both 4-MPD and
mephedrone (Wikipedia)
carry a para-methyl phenyl ring, but 4-MPD has a longer pentyl backbone chain
(five carbons) versus mephedrone’s propyl chain (three carbons). This chain
length difference increases molecular weight from 177.24 g/mol (4-MMC) to
205.3 g/mol and produces a measurably longer HPLC retention time — making them
analytically separable in cathinone screening panels.
What purity does Chemnexis Pharma supply 4-MPD at?
Every batch is independently HPLC-tested to ≥98% purity — matching the analytical
reference material benchmark set by Cayman Chemical for this compound. The
batch-specific COA documents lot number, test date, analytical method, and verified
purity result. For standards refer to 4-MPD (4-Methylpentedrone)

Is wholesale and bulk 4-MPD pricing available?
Yes. Chemnexis Pharma offers wholesale and bulk
4-MPD (4-Methylpentedrone) pricing across all volume tiers.
All bulk orders include batch-specific COA. Contact
sales@chemnexispharma.com
for a personalised price per kg quote.
Which countries does Chemnexis Pharma ship 4-MPD 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 →
What is the relationship between 4-MPD and pentedrone?
4-MPD is the p-methyl derivative of pentedrone — meaning it is
structurally identical to pentedrone but with an additional methyl group at the
para-position of the phenyl ring. This methyl substitution shifts the compound’s
chromatographic and physicochemical properties relative to unsubstituted pentedrone.
For NPS framework context refer to the
EMCDDA NPS overview →
Does the order include SDS documentation?
Yes. SDS documentation is available on request alongside the batch COA for all
4-MPD orders from Chemnexis Pharma.
