India classifies 2-Bromo-4-Methylpropiophenone as controlled substance to curb mephedrone
Synopsis
India has moved to choke mephedrone at its chemical root — by classifying its key precursor, 2-Bromo-4-Methylpropiophenone, as a controlled substance. With NCB raids already recovering large mephedrone hauls nationwide, the Centre is betting that cutting off the supply chain upstream will do what enforcement alone has not.
Key Takeaways
The Department of Revenue notified 2-Bromo-4-Methylpropiophenone as a controlled substance on 15 June 2026 under the NDPS (RCS) Order, 2013.
The chemical is a primary precursor used in the illicit manufacture of mephedrone , a synthetic party drug seized in large quantities by the NCB in recent months.
All dealers, manufacturers, importers, and exporters must register with the NCB Zonal Director using Form A ; application deadline is 7 August 2026 .
Existing stock holders must disclose inventory as of 30 June 2026 to the NCB on or before 10 July 2026 via Form X .
Non-compliance after 7 September 2026 attracts penal action under Section 25A of the NDPS Act, 1985.
The Department of Revenue, Ministry of Finance, has formally notified 2-Bromo-4-Methylpropiophenone as a controlled substance under the Narcotic Drugs and Psychotropic Substances (Regulation of Controlled Substances) Order, 2013, effective 15 June 2026. The move targets the chemical's growing role as a key precursor in the illicit manufacture of mephedrone (4-methylmethcathinone), a synthetic psychotropic drug that has seen a sharp spike in seizures across India.
Why the Centre Acted
Mephedrone — widely used as a party drug — has been recovered in large quantities during Narcotics Control Bureau (NCB) raids across the country over the past several months. Officials believe that controlling the supply of 2-Bromo-4-Methylpropiophenone, the chemical precursor from which mephedrone is synthesised, is the most effective upstream intervention to disrupt production. This classification represents a regulatory escalation beyond previous enforcement-only approaches.
What the Notification Requires
Under the official notification dated 15 June 2026, all persons and entities engaged in the manufacture, distribution, sale, purchase, possession, storage, consumption, import, or export of 2-Bromo-4-Methylpropiophenone — including those operating through websites, social media platforms, or other electronic channels — are required to obtain a registration number in Form A from the jurisdictional Zonal Director of the NCB, in accordance with the NDPS (RCS) Order, 2013.
The notification further states: 'All such firms/entities are requested to submit registration applications in Form B to the concerned NCB Zonal Unit well in advance, i.e., on or before August 7, 2026, so that the registration number is issued by NCB within the statutory period of 180 days from March 11, 2026.'
Stock Disclosure Deadline
All manufacturers, traders, distributors, importers, exporters, and any other parties holding existing stocks of the substance have been directed to furnish details of stock held as of 30 June 2026 to the jurisdictional Zonal Director, NCB, on or before 10 July 2026, using Form X. This inventory disclosure is designed to give regulators a baseline picture of how widely the chemical is currently in circulation.
Penalties for Non-Compliance
The notification carries a clear enforcement deadline: any person or entity dealing with 2-Bromo-4-Methylpropiophenone in violation of the NDPS Act, 1985 after 7 September 2026 will be liable for penal action under Section 25A of the Act. Prescribed forms, detailed procedures, and jurisdictional details of NCB Zonal Units are available on the NCB Precursors Portal. This is a significant deterrent, as Section 25A carries substantial penalties for entities that fail to comply with controlled-substance regulations.
Point of View
And the registration regime is only as strong as the NCB's capacity to verify compliance. The 180-day window from March 2026 also suggests the government had been tracking this chemical well before the public notification, which raises questions about why action was not taken sooner given the scale of recent seizures.

Frequently Asked Questions
What is 2-Bromo-4-Methylpropiophenone and why has India banned it?
2-Bromo-4-Methylpropiophenone is a chemical compound used as a key precursor in the illicit manufacture of mephedrone, a synthetic psychotropic drug. India's Department of Revenue classified it as a controlled substance on 15 June 2026 to disrupt mephedrone production at the supply-chain level, following a surge in NCB seizures of the finished drug.
What is mephedrone and why is it a concern?
Mephedrone (4-methylmethcathinone) is a synthetic narcotic commonly used as a party drug and listed as a psychotropic substance under the NDPS Act. Large quantities have been seized by the NCB across India in recent months, prompting the Centre to act against its chemical precursor.
What must businesses dealing in this chemical do now?
All entities manufacturing, trading, importing, exporting, or otherwise dealing in 2-Bromo-4-Methylpropiophenone — including online sellers — must obtain a registration number in Form A from the jurisdictional NCB Zonal Director and submit a registration application in Form B by 7 August 2026.
What is the deadline to declare existing stocks?
Entities holding stocks of 2-Bromo-4-Methylpropiophenone must disclose inventory held as of 30 June 2026 to the NCB Zonal Director on or before 10 July 2026, using Form X available on the NCB Precursors Portal.
What penalties apply for non-compliance?
Any person or entity found dealing in the substance in violation of the NDPS Act, 1985 after 7 September 2026 will face penal action under Section 25A of the Act, which carries significant legal consequences for non-compliant manufacturers, traders, and distributors.
