Buy 4-CEC (4-Chloroethcathinone) Online — Certified Purity, Wholesale & Retail
4-CEC (4-Chloroethcathinone), formally named
1-(4-chlorophenyl)-2-(ethylamino)propan-1-one, is a chlorinated synthetic cathinone
with molecular formula C₁₁H₁₄ClNO and molecular weight
211.69 g/mol. A member of the
substituted cathinone class (Wikipedia),
it is defined by a para-chlorine substituent on the phenyl ring and an N-ethyl
secondary amine — the N-ethyl configuration distinguishing it structurally from
4-CMC (N-methyl) and producing a distinct analytical profile. Chemnexis Pharma
is the leading supplier, delivering batch-verified material with a full Certificate
of Analysis. Full structural data: 4-CEC (4-Chloroethcathinone)

Structural & Analytical Profile
4-CEC occupies a distinct position within the chlorinated cathinone
subclass. Its para-chlorine substituent generates the characteristic chlorine isotope
pattern (³⁵Cl/³⁷Cl approximately 3:1) under mass spectrometric analysis — providing
an unambiguous halogen identification marker across multi-analyte screening panels.
The N-ethyl secondary amine differentiates it analytically from
4-CMC (clephedrone, Wikipedia),
which carries an N-methyl group — producing different retention times under
reversed-phase HPLC despite both compounds sharing the para-chloro phenyl ring.
As confirmed by the DEA Reference Material Collection and listed by Cayman Chemical
as an
analytical reference material at ≥98% purity,
the compound is well-established in forensic reference standard libraries.

Frequently Asked Questions — 4-CEC (4-Chloroethcathinone)
What is 4-CEC (4-Chloroethcathinone)?
4-CEC (4-Chloroethcathinone) is a chlorinated synthetic cathinone
with molecular formula C₁₁H₁₄ClNO and molecular weight 211.69 g/mol. Its IUPAC name
is 1-(4-chlorophenyl)-2-(ethylamino)propan-1-one. It carries a para-chlorine on the
phenyl ring and an N-ethyl amine group. Full data:
PubChem CID 31004 →
How does 4-CEC differ from 4-CMC?
Both compounds carry a para-chlorine on the phenyl ring, but
4-CEC has an N-ethyl amine group while
4-CMC (clephedrone) →
has an N-methyl group. This amine difference changes the molecular weight
(211.69 vs 197.66 g/mol) and produces distinct chromatographic retention times
under HPLC and LC-MS/MS, enabling analytical differentiation in screening panels.
What purity does Chemnexis Pharma supply 4-CEC at?
Every batch is independently HPLC-tested to ≥98% purity — matching the analytical
reference material purity tier confirmed by Cayman Chemical for this compound.
The batch-specific COA documents lot number, test date, method, and purity result

Is wholesale and bulk 4-CEC pricing available?
Yes. Chemnexis Pharma offers wholesale and bulk
4-CEC (4-Chloroethcathinone) pricing across all volume tiers —
all orders include batch-specific COA regardless of quantity. Contact
sales@chemnexispharma.com
for a personalised price per kg quote.
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 →
What analytical significance does the chlorine isotope pattern have?
The para-chlorine substituent in 4-CEC generates a characteristic
³⁵Cl/³⁷Cl isotope pattern (approximately 3:1 ratio) under mass spectrometric
analysis. This halogen fingerprint provides an unambiguous identification marker
across multi-analyte forensic screening panels, making the compound reliably
identifiable in complex sample matrices. For broader chlorinated cathinone context
see the
EMCDDA NPS overview →
Does the order include SDS documentation?
Yes. SDS documentation is available on request alongside the batch COA for all
orders from Chemnexis Pharma.
