Description
Fludiazepam, a benzodiazepine derivative, is an analytical reference standard that is regulated as a Schedule IV compound in the United States. It is primarily intended for research and forensic applications. Fludiazepam possesses anxiolytic, anticonvulsant, sedative, and skeletal muscle relaxant properties, making it a versatile compound in the pharmaceutical industry.
Uses
Used in Pharmaceutical Industry:
Fludiazepam is used as a therapeutic agent for its anxiolytic properties, helping to alleviate anxiety and stress in patients. Its sedative effects also make it useful for treating insomnia and other sleep disorders.
Fludiazepam is used as an anticonvulsant for controlling seizures and preventing convulsions in patients with epilepsy or other seizure disorders.
In the field of anesthesia, Fludiazepam is used as a sedative to calm patients before medical procedures, promoting relaxation and reducing anxiety.
Fludiazepam is also used as a skeletal muscle relaxant to alleviate muscle spasms and pain, particularly in conditions such as muscle strains, sprains, or spasmodic torticollis.
Used in Research and Forensic Applications:
Fludiazepam is used as a research compound for studying the effects of benzodiazepines on the central nervous system and their potential applications in various medical conditions.
In forensic applications, Fludiazepam may be used to detect and analyze the presence of benzodiazepines in biological samples, such as blood or urine, for legal or investigative purposes.

Manufacturing Process
A solution of 60 g of chromic anhydride in 40ml of water was added dropwise
to a suspension of 60 g of 2-aminomethyl-1-methyl-5-chloro-3-(ofluorophenyl)-
indole hydrochloride in 600 ml of acetic acid. The mixture was
stirred at room temperature overnight. To the reaction mixture was added 1.1
liters of ether and 1 liter of water and then 800 ml of 28% ammonium
hydroxide, in small portions. The ethereal layer separated, washed with water,
dried, and concentrated under reduced pressure. The residue (51.8 g) was
dissolved in 100 ml of ethanol, and 100 ml of 20% ethanolic hydrogen
chloride was added to the solution and the mixture was cooled. The
precipitate was collected by filtration to yield 46.5 g of 1-methyl-7-chloro-5-
(o-fluorophenyl)-1,3-dihydro-2H-1,4-benzodiazepine-2-one hydrochloride,
melting point 218°C (decomposed). Recrystallization from ethanol raised the
melting point to 218.5°C to 219°C (decomposed).

Check Digit Verification of cas no
The CAS Registry Mumber 3900-31-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,0 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3900-31:
(6*3)+(5*9)+(4*0)+(3*0)+(2*3)+(1*1)=70
70 % 10 = 0
So 3900-31-0 is a valid CAS Registry Number.

Synthesis and Spectral Properties of 7-Chloro-5-[(o- and p-R1)phenyl]-1-R2-3H-[1,4]benzodiazepin-2-ones
Cortes, Eduardo Cortes,Martinez, Isidro Ebromares,Mellado, Olivia Garcia
, p. 1189 - 1194 (2007/10/03)
A series of twelve new 7-chloro-5-[(o- and p-R1)phenyl]-1-R2-3H-[1,4] benzo-diazepin-2-ones, which have possible pharmocological properties were synthesized. The synthesis of all the final compounds was carried out by four steps. The structure of all final products was corroborated by ir, 1H nmr, 13C nmr and ms, and have been obtained in 35-94 percent yield.
