3-MEC (3-Methylethcathinone), formally named
2-(ethylamino)-1-(3-methylphenyl)-1-propanone, is a substituted cathinone compound
with molecular formula C₁₂H₁₇NO and molecular weight
191.27 g/mol. Structurally related to

4-MEC (Wikipedia),
it carries a methyl substituent at the meta (3-) position of the phenyl ring and an
N-ethyl secondary amine — a configuration that produces a chromatographically distinct
profile from its para and ortho positional isomers. Chemnexis Pharma supplies
batch-verified material with a full Certificate of Analysis to buyers worldwide.

Structural & Analytical Profile

3-MEC is the meta-methyl isomer of the methylethcathinone series —
occupying the 3-position on the phenyl ring as opposed to the para (4-) position of
4-MEC. Both compounds share the N-ethyl secondary amine group, making the methyl ring
position the sole structural differentiator. Under reversed-phase HPLC conditions, this
positional difference produces measurably distinct retention times, enabling analytical
separation from 4-MEC and 2-MEC in multi-analyte cathinone screening panels.

Under LC-MS/MS, the compound generates a fragmentation pattern consistent with the
methylphenyl-ethylaminopropanone scaffold — with characteristic loss of the ethylamine
group producing a diagnostic base peak. Its classification within the synthetic
cathinone class by the
EMCDDA NPS framework →
confirms its relevance as a forensic reference standard. Cayman Chemical lists
3-Methylethcathinone as an

analytical reference standard at ≥98% purity
— the benchmark Chemnexis Pharma meets or exceeds on every batch. Browse our full
