On 11 March 2026 the Department of Revenue amended the Narcotic Drugs and Psychotropic Substances (Regulation of Controlled Substances) Order, 2013. The amendment placed the chemical 2‑Bromo‑4‑Methylpropiophenone on the list of controlled substances. The decision came after law‑enforcement agencies uncovered clandestine laboratories using this compound to manufacture mephedrone, a synthetic stimulant.
Background
2‑Bromo‑4‑Methylpropiophenone is an aromatic ketone used as an intermediate in organic synthesis. It appears as an off‑white crystalline powder and dissolves readily in organic solvents such as ethanol and acetone. Industries use the compound to produce pharmaceuticals, agrochemicals and fine chemicals. However, it is also a key precursor for synthesising mephedrone (4‑methylmethcathinone), a psychoactive drug banned in India. Mephedrone laboratories in Rajasthan, Gujarat, Maharashtra and Telangana had sourced large quantities of this chemical before the amendment.
Reason for regulation
- Drug control: Classifying the compound as a controlled substance makes it illegal to manufacture, distribute or possess it without appropriate licences.
- Clandestine labs: Enforcement agencies seized tonnes of mephedrone in recent years. The National Crime Bureau reported that mephedrone seizures increased from hundreds of kilograms in 2020 to several thousand kilograms in 2024. Controlling precursor chemicals aims to stem this growth.
- Compliance requirements: Licensed chemical firms must now maintain records of production, sales and transport of 2‑Bromo‑4‑Methylpropiophenone. Authorities can inspect facilities and impose penalties for non‑compliance.
Impact
By regulating this compound the government seeks to curb the manufacture of mephedrone and other synthetic drugs. Stricter monitoring may increase production costs for legitimate users, but it will help law‑enforcement agencies track suspicious movements of precursor chemicals. This is the eighth substance added to Schedule A of the NDPS (Regulation of Controlled Substances) Order.
Conclusion
The inclusion of 2‑Bromo‑4‑Methylpropiophenone in the controlled substances list reflects India’s determination to break drug supply chains. Tightening control over precursor chemicals is an effective strategy to prevent the proliferation of synthetic stimulants and protect public health.
