Abstract:
2-Ethylamino-1-phenylbutane (EAPB) and 2-amino-1-phenylbutane (APB) were identified by gas chromatography-mass spectrometry in multiple urine samples submitted for stimulant drug testing and screened positive for amphetamines by enzyme immunoassay. Forty-two samples from all over the USA were found, containing both analytes during a 3-month period May-July 2013. A sports dietary supplement 'CRAZE' has been determined to be one of the sources of EAPB supply. EAPB along with its suggested metabolite APB were detected in a urine sample, obtained from a person known to use 'CRAZE'.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.

Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
