3-CMC Crystal Powder

Introduction

3-CMC crystal powder is 1-(3-chlorophenyl)-2-(methylamino)propan-1-one. It is a substituted cathinone. A chlorine sits at the meta position of the phenyl ring, and the side chain is N-methyl. It is the 3-chloro analogue of methcathinone. It is not 4-CMC, which has the chlorine at the para position, and it is not 3-MMC, which has a methyl group instead of chlorine.

It has been sold as a designer cathinone and is not an approved medicine. The free base is unstable in many cathinone lots, so crystal powder is often the hydrochloride. The free base weighs 197.66 g·mol−¹. The hydrochloride weighs about 234.1 g·mol−¹. The label must state which form is supplied. The alpha carbon is a stereocenter, so racemate versus a named enantiomer should also be stated.

Key features and benefits – Buy 3-CMC Crystal Powder

• Meta-chloro cathinone. The chlorine position is the structural difference from 4-CMC and is visible by NMR and mass spectrometry.
• Documented identity. Free base CAS 1049677-59-9, formula C10H12ClNO. Hydrochloride CAS 1607439-32-6.
• Chlorine marker. Mass spectra should show an M / M+2 pair from the ring chlorine.
• Weighable solid. Suitable for reference standards when the COA confirms form and chlorine position.
• Laboratory-only handling. Intended for controlled chemical and in vitro work, not for formulation or human administration.

Specifications Of Buy 3-CMC Crystal Powder

Applications in research

Appropriate uses are non-clinical and institutionally approved:

• Analytical reference for HPLC, LC-MS, and NMR identification of 3-CMC.
• Forensic differentiation from 4-CMC, 3-MMC, and 4-MMC.
• Comparison of free-base and hydrochloride lots.
• Impurity profiling of the chlorocathinone.

Do not describe or imply oral use, insufflation, or any other human route.

Purity and testing

A defensible product claim rests on the batch certificate.

• HPLC for chromatographic purity, with retention that separates the 3-chloro isomer from the 4-chloro isomer.
• 1H NMR for the meta-chloro aromatic pattern and the N-methyl. A para-disubstituted pattern means 4-CMC.
• Mass spectrometry for the free-base molecular ion consistent with C10H12ClNO, including the chlorine isotope pair. Mass alone does not separate 3-CMC from 4-CMC.
• Explicit statement of free base or hydrochloride.
• Statement of racemate versus enantiomer.
• Residual solvent if the supplier states it.

Store the COA with the lot number. Do not use a 4-CMC CAS number for this powder.

Disclaimer

For laboratory research use only. Not for human or veterinary consumption, not for diagnostic or therapeutic use, and not a food, drug, or cosmetic. 3-CMC is a Class B substance in the United Kingdom and is Anlage II in Germany. It is illegal in China and Sweden. Other jurisdictions may treat it as a cathinone analogue. Buyers are responsible for confirming legality, licensing, import rules, and institutional approval before ordering or handling. Handle with standard laboratory PPE and dispose of waste under local hazardous-chemical rules. No statement on this page is a claim of safety, efficacy, or fitness for any human application.

Frequently asked questions

What is 3-CMC?
It is 3-chloromethcathinone, 1-(3-chlorophenyl)-2-(methylamino)propan-1-one, also called clophedrone. The free base is C10H12ClNO, 197.66 g·mol−¹.

Is the crystal the free base?
Not unless the COA says so. The hydrochloride is CAS 1607439-32-6 and weighs about 234.1 g·mol−¹. Crystal habit does not identify the salt.

Is this the same as 4-CMC or 3-MMC?
No. 4-CMC has the chlorine at the para position and the same formula. 3-MMC has a methyl group instead of chlorine. 3-CMC is the meta-chloro cathinone, CAS 1049677-59-9.

Which CAS number applies?
CAS 1049677-59-9 for the free base. CAS 1607439-32-6 for the hydrochloride. Use the number that matches the form on the COA.

What purity is supplied?
Only the figure on the lot COA. The method should separate 3-CMC from 4-CMC.

How should it be stored?
Sealed, cool, dry, and protected from light. The free base is less stable than the salt. Record the lot number with the COA.

Can it be used in humans?
No. It is not an approved medicine and is not sold for consumption. In the United Kingdom it is Class B. Check local law before purchase.

What analytical methods confirm identity?
HPLC with isomer resolution, NMR for the meta-chloro pattern, and mass spectrometry consistent with C10H12ClNO, including the chlorine isotope pair. Mass alone does not separate it from 4-CMC. The COA should state free base or salt.
