Alpha PHP

Alpha-PHP (α-Pyrrolidinohexanophenone) Certified Reference Solution

GCS Laboratories supplies alpha-PHP certified reference material (CRM) as a high-purity solution designed for the calibration and validation of analytical methods used in forensic toxicology, clinical toxicology, and seized-drug analysis. This product is intended exclusively for licensed laboratory professionals engaged in the detection and quantification of synthetic cathinones in biological matrices and evidentiary samples.

Alpha-PHP (chemical name: 1-phenyl-2-(pyrrolidin-1-yl)hexan-1-one; also known as α-PHP, PV-7) is a synthetic cathinone that emerged on the illicit drug market and has been associated with severe adverse events, including fatalities, across multiple jurisdictions. The substance has no recognized therapeutic use and is controlled under international conventions. Consequently, reliable analytical standards are essential for laboratories tasked with identifying alpha-PHP in postmortem blood, antemortem serum, urine, and seized materials.

Note: This product is a controlled substance in many jurisdictions (including Schedule I in the United States and Schedule II under the 1971 Convention on Psychotropic Substances). Orders require verification of the purchaser’s controlled-substance license or institutional permit. GCS Laboratories does not sell to unlicensed individuals.

Product Specifications

Analytical Applications

Alpha-PHP reference material is suitable for:

• LC-MS/MS method development and validation for synthetic cathinone quantification in blood, serum, urine, and tissue homogenates
• GC-MS confirmation of alpha-PHP identity in seized-drug exhibits
• Isomer discrimination — alpha-PHP must be chromatographically separated from its structural isomer alpha-PiHP (α-pyrrolidinoisohexanophenone), a distinction critical for accurate forensic interpretation
• Calibration curve preparation across clinically relevant concentration ranges

Published forensic literature indicates that alpha-PHP concentrations in biological matrices vary substantially. Reported serum concentrations in intoxication cases have ranged from 4 to 10 ng/mL, while postmortem blood concentrations have been documented between 12 and 701 ng/mL in fatal cases. Laboratories should validate their methods across these ranges using matrix-matched calibrators.

Why Choose GCS Laboratories Reference Materials?

First-hand analytical expertise. Every lot of alpha-PHP CRM undergoes independent verification by our in-house analytical team using validated LC-MS/MS and GC-MS protocols. We do not simply resell third-party materials — each batch is accompanied by a certificate of analysis (CoA) documenting purity, concentration, and stability data specific to that lot.

Isomer-aware quality control. We recognize that

is frequently confused with alpha-PiHP in forensic casework. Our CoA includes explicit confirmation of isomeric purity, and our technical team can provide chromatographic conditions suitable for baseline separation of these closely related cathinones.

Regulatory compliance support. Each shipment includes documentation to support your laboratory’s chain-of-custody requirements. We verify purchaser credentials before dispatch and maintain records in accordance with controlled-substance distribution regulations.

Technical consultation. Our application scientists are available to discuss method optimization, matrix effects, and concentration ranges relevant to your specific forensic or clinical toxicology workflow.

Safety and Handling

Hazard Classification (solution in methanol): Acute Toxicity Category 3 (oral, dermal, inhalation); Flammable Liquid Category 2; Specific Target Organ Toxicity (single exposure) Category 1.

Required Personal Protective Equipment: Nitrile gloves, laboratory coat, chemical splash goggles, and fume hood. Methanol is highly flammable and toxic; handle in accordance with institutional chemical hygiene plans.

Disposal: Dispose of unused material and empty ampoules as hazardous waste in accordance with local, state, and federal regulations.

Ordering and Licensing Requirements

Alpha-PHP is a controlled substance in the following jurisdictions (non-exhaustive):

• United States: Schedule I (DEA)
• Germany: Controlled under BtMG (Betäubungsmittelgesetz); a permit under §3 BtMG is required for purchase
• United Kingdom: Class B
• International: Schedule II of the 1971 Convention on Psychotropic Substances

To order: Submit a completed Controlled Substance Purchaser Verification Form along with a copy of your institutional license or permit. Orders are shipped only to verified laboratory addresses. GCS Laboratories reserves the right to refuse any order that does not meet regulatory requirements.
