Adulterant detection: High-potency analogues (4F-MPH, 3,4-CTMP) are dangerous substitutes. Reagent profiles are similar — GCMS needed for definitive differentiation.
Reagent testing can confirm methylphenidate-class compound but cannot reliably distinguish between specific analogues. Fentanyl strips recommended for pressed pills sourced from illicit markets.
