Description
5-Propyl-1,3-benzenediol, also known as 5-Propylbenzene-1,3-diol, is a white to brown crystalline solid that serves as an intermediate in the preparation of various compounds. It is characterized by its unique chemical structure, which contributes to its specific properties and applications.
Uses
Used in Pharmaceutical Industry:
5-Propyl-1,3-benzenediol is used as an intermediate for the preparation of Cannabigerovarin (C175140), a compound that stimulates thermosensitive transient receptor potential (TRP) channels of vanilloid type-4 (TRPV4). This stimulation leads to an increase in intracellular calcium ion concentration ([Ca2+]i) with moderate-high efficacy (30-60% of the effect of ionomycin) and potency (EC50 0.9-6.4 μM). 5-Propyl-1,3-benzenediol has potential applications in the development of drugs targeting TRPV4 channels, which are involved in various physiological processes and diseases.
Synthesis
In a 100 mL round bottom flask, open to the atmosphere was added the crude product Benzene, 1,3-dimethoxy-5-propyl (0.736 g, 4.08 mmol, 1.0 equiv.) and a 1:1 mixture of glacial acetic acid (20 mL, 349.7 mmol, 17.4 M) and hydrobromic acid (48% in H2O, 20 mL, 368.3 mmol, 18.4 M). The reaction mixture was refluxed at 125 °C for 3 hours while stirring, or until the starting material was consumed via TLC analysis. At this point, the reaction was allowed to cool to room temperature and quenched by the addition of DI H2O. The biphasic solution was added to a separatory funnel, wherein the organic portion was extracted Et2O (ca. 3x 20 mL). The organic layers were then combined, neutralized with a concentrated sodium bicarbonate solution (ca. 30 mL), washed with a saturated brine solution (ca. 50 mL), dried over MgSO4, filtered, and concentrated in vacuo to afford the final product without 5-Propyl-1,3-benzenediol (0.609 g, 99% yield) as a pale yellow oil.
Solubility in organics
5-Propyl-1,3-benzenediol is soluble in N,N-dimethylformamide, soluble in methanol, slightly soluble in glacial acetic acid, very slightly soluble in chloroform, almost insoluble in water.
Check Digit Verification of cas no
The CAS Registry Mumber 500-49-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 500-49:
(5*5)+(4*0)+(3*0)+(2*4)+(1*9)=42
42 % 10 = 2
So 500-49-2 is a valid CAS Registry Number.

A Novel and Practical Continuous Flow Chemical Synthesis of Cannabidiol (CBD) and its CBDV and CBDB Analogues

Cannabidiol is one of the main non-psychoactive cannabinoids present in Cannabis sativa and, in the last decade, it is gaining great interest among the scientific community for its pharmaceutical, nutraceutical, and cosmetic applications. Herein, we report the first continuous flow chemical synthesis of cannabidiol (CBD) and its analogues cannabidivarin (CBDV) and cannabidibutol (CBDB). This approach permits to synthesize products in very good yields (55–59 %), limiting the formation of psychoactive and illegal cannabinoids such as tetrahydrocannabinol (THC).

, (2017/01/31)
The present disclosure relates to the preparation of a cannabidiol compound or a derivative thereof. The cannabidiol compound or derivatives thereof can be prepared by an acid-catalyzed reaction of a suitably selected and substituted di-halo-olivetol or derivative thereof with a suitably selected and substituted cyclic alkene to produce a dihalo-cannabidiol compound or derivative thereof. The dihalo-cannabidiol compound or derivative thereof can be produced in high yield, high stereospecificity, or both. It can then be converted under reducing conditions to a cannabidiol compound or derivatives thereof.
