SL-164: Chemical Properties, Research Applications, and Safety Data

SL-164 is a synthetic quinazolinone compound of interest to researchers and forensic laboratories due to its relationship to methaqualone and its unique chemical structure. Other names: dicloqualone CAS Registry Number: 3476-88-8 Unlike an approved medicine, SL-164 is mostly discussed in analytical, forensic and research contexts.

SL-164: What’s that?

SL-164 is a methaqualone chemical class quinazolinone derivative. The formal chemical name for it is 5-chloro-3-(4-chloro-2-methylphenyl)-2-methyl-4(3H)-quinazolinone. This compound has 2 chlorine atoms and a molecular formula of C16H12Cl2N2O. Its molecular weight is listed on PubChem as 319.2 g/mol (approximately).

The structure of SL-164 is similar to compounds known to possess sedative and hypnotic activity and this is why researchers became interested in it. But structural similarities do not mean that SL-164 has the same safety profile or approved medical uses as any other compound.

Chemical Characterisation of SL-164

Labs can distinguish SL-164 from other compounds using a few identifiers:

• Name: SL164
• Synonym: Dicloqualon
• CAS No: 3476-88-8
• Molecular Formula: C16H12Cl2N2O
• Molecular weight: 319.2 g per mol
• Chemical family: Quinazolinone
• 5-Chloro-2-methyl-3-(4-chloro-2-methylphenyl)quinazolin-4(3H)one IUPAC

Labs rely on analytical techniques rather than just a product label because many compounds share similar names or molecular properties.

SL164 Applications for Research and Analysis

SL-164 is particularly interesting for forensic toxicology and analytical chemistry. Researchers can use advanced laboratory techniques to identify compounds in biological samples and differentiate them from other psychoactive substances.

In a published forensic investigation, scientists used LC-QTOF-MS (liquid chromatography coupled with quadrupole time-of-flight mass spectrometry) to investigate an unknown substance. The researchers subsequently identified the compound, SL-164, and verified its identity and purity using other analytical techniques, such as nuclear magnetic resonance spectroscopy.

Hence, SL-164 can be an important example in the identification of emerging psychoactive compounds in forensic laboratories.

Laboratory and Physical Data

SL-164, a commercial analytical reference standard, appears as a crystalline solid with a purity of ≥98% for this specific product. The same source indicates that researchers and forensic professionals should store the material at -20°C. These specifications target that reference standard and do not apply automatically to all materials sold under the SL164 name.

Why is SL164 Significant in Research?

The significance of SL164 is in part derived from its association with the broader family of methaqualone related compounds. Thus, analytical laboratories may find it during analysis of unknown or newly appearing substances.

Forensic scientists require reliable identification methods because an unknown compound may give initial analytical results that appear to be similar to some other substances. The published case of SL164 illustrates why researchers compare accurate mass, isotope patterns, retention behaviour, fragmentation data and reference standards before they can arrive at a definitive conclusion.

Safety Information:

SL164 is not an approved drug, dietary supplement or general wellness product. The compound has been linked to sedative effects in the scientific literature and has been reported in forensic toxicology reports of investigations of intoxication.

Such information should thus be held in an appropriate research, analytical or forensic setting. This article is not a guide to human consumption, recreational use, dosing or how to procure the compound.

Final Review

SL164 is a quinazolinone compound and methaqualone analogue . Molecular Formula C16H12Cl2N2O . CAS Number 3476-88-8 . Researchers in the fields of analytical chemistry and forensic toxicology mainly investigate it. Laboratories can employ sophisticated methods like LC-QTOF-MS and NMR to accurately identify and characterise the compound.

SL164 exhibits sedative effects and appears in forensic toxicology, prompting researchers to adhere to all relevant laboratory safety procedures and regulations when handling the compound. Do not promote it as an authorised medicinal product.
