1609-66-1 Usage

Description

Norfentanyl (Item No. ISO60195) is a certified reference material that is classified as an opioid. It is a thermal degradant and major urinary metabolite of the opioid analgesic, fentanyl (Item Nos. ISO60197 | 14719). This product is intended for forensic and research applications.

Chemical Properties

light yellow powder

Uses

Norfentanyl is a major urinary metabolite of a narcotic analgesic fentanyl.

Definition

ChEBI: A monocarboxylic acid amide resulting from the formal condensation of the aryl amino group of 4-(N'-phenyl)piperidin-4-amine with propanoic acid. A major metabolite of fentanyl.

Check Digit Verification of cas no

The CAS Registry Mumber 1609-66-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,0 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1609-66:
(6*1)+(5*6)+(4*0)+(3*9)+(2*6)+(1*6)=81
81 % 10 = 1
So 1609-66-1 is a valid CAS Registry Number.

A convenient synthetic pathway for 14C labeling of fentanyl [N-(1-phenethyl-4-piperidinyl)- propionanilide], a widely used narcotic analgesic agent, with good radiochemical yield was developed.

Fentanyl [N-(1-phenethyl-4-piperidinyl)propionanilide] is a popular narcotic analgesic agent that is clinically used worldwide. However, fentanyl and its several analogs have caused abuse and fatalities in humans due to overdosing and narrow therapeutic index. The present study reports the synthesis and comparative bioefficacy of fentanyl and its four analogs, viz., N-(1-propyl-4-piperidinyl)propionanilide (1), N-(1-(2-phenoxyethyl)-4- piperidinyl)propionanilide (2), N-(1-(3-phenoxypropyl)-4-piperidinyl) propionanilide (3) and N-(1-(2-cyanoethyl)-4-piperidinyl)propionanilide (4), where the phenethyl chain of fentanyl was replaced by different functional groups, viz., alkyl, ethereal, and nitrile moieties. The median lethal dose (LD50) of the compounds was determined by three different routes and all the analogs were found to be safer than fentanyl. Observational assessment on spontaneous activities of the central nervous system, peripheral nervous system, and autonomic nervous system revealed that all the analogs were similar to fentanyl. Further, the neurotoxic effects of all the analogs were reversed by naloxone hydrochloride (opioid antagonist), confirming that their effects were mediated through opioid receptors. Antinociceptive activity was displayed by all the compounds and their median effective dose (ED50) and analgesic potency ratio were more or less similar to fentanyl. The lowest ED50 (23.7) and the highest potency ratio (1.18) was observed in the case of 2. However, the maximum therapeutic index was afforded by 4. The study indicates the promising role of some new opioid analgesics.
