  • Cathinone test
    Patent number: 11808775
    Abstract: A method of detecting the presence of a cathinone moiety in a sample, such as a suspected illicit drug sample, which comprises contacting the sample with a solution comprising neocuproine, a source of copper(II) and a catalyst and observing a colour change, where present, that correlates with the presence of cathinone. The method is operable at environmental temperature. Mechanical elements may be employed to accelerate the colour change if desired.
    Type: Grant
    Filed: November 15, 2018
    Date of Patent: November 7, 2023
    Inventors: Shanlin Fu, Morgan Philp, Ronald Shimmon
  • IN-FIELD COLOUR TEST FOR SCREENING FENTANYL AND ANALOGUES THEREOF
    Publication number: 20230349935
    Abstract: A method of detecting the presence of fentanyl or a fentanyl analogue in a sample which comprises contacting the sample with a 1,2 naphthoquinone (such as 1,2-naphthoquinone itself) in a solvent, preferably acetonitrile, and observing a colour change, which when present, correlates with the presence of fentanyl or a fentanyl analogue. Optionally, a buffer may be provided to maintain an alkaline environment and/or a metal halide catalyst and/or light source may be added to accelerate colour development.

  • NBOMe test
    Patent number: 11761954
    Abstract: A method of detecting the presence of an NBOMe in a sample which comprises of contacting the sample with an activated p-quinone such as 2,3,5,6-tetrachloro-1,4-benzoquinone (TCBQ) and an aldehyde, for example acetaldehyde, and optionally a buffer and observing a colour change, which when present, correlates with the presence of an NBOMe. The ingredients may be provided in the form of a kit which can include a colour standard or comparison chart.
