562-10-7 Usage
Uses
Different sources of media describe the Uses of 562-10-7 differently. You can refer to the following data:
1. H1 Histamine receptor antagonist. Antihistaminic; sedative; hypnotic.
2. antihistaminic, hypnotic
3. Doxylamine succinate salt has been used as a therapeutic drug to check developmental toxicity.
General Description
Different sources of media describe the General Description of 562-10-7 differently. You can refer to the following data:
1. The acid succinate salt (bisuccinate)of doxylamine, 2-[ -[2-(dimethylamino)ethoxy]- -methylbenzyl]pyridine bisuccinate (Decapryn Succinate), isa white to creamy-white powder with a characteristic odor.It is soluble in water (1:1), alcohol (1:2), and chloroform(1:2). A 1% solution has a pH of about 5.Doxylamine succinate is comparable in potency todiphenhydramine. It is indicated for the relief of seasonalrhinitis symptoms, but is also used as a nighttime sedative.Concurrent use of alcohol and other CNS depressantsshould be avoided.
2. White or creamy white powder. pH (1% aqueous solution) between 4.9 and 5.1.
Air & Water Reactions
Water soluble.
Health Hazard
SYMPTOMS: Symptoms of exposure to Doxylamine succinate may include drowsiness, excitability, nervousness, dizziness and sleeplessness.
Fire Hazard
Flash point data for Doxylamine succinate are not available. Doxylamine succinate is probably combustible.
Biochem/physiol Actions
H1 histamine receptor antagonist; hypnotic.Doxylamine suppresses histamine at the H1 receptor. It is associated with the short term management of insomnia and temporary relief of common cold symptoms. On the other hand, doxylamine intoxication is linked with rhabdomyolysis and secondary acute renal failure.Studies in mice show that doxylamine induces liver microsomal cytochrome P450 and other enzymes involved in thyroxine (T4) metabolism. In combination with pyridoxine hydrochloride, this drug is used to treat morning sickness.
Check Digit Verification of cas no
The CAS Registry Mumber 562-10-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 2 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 562-10:
(5*5)+(4*6)+(3*2)+(2*1)+(1*0)=57
57 % 10 = 7
So 562-10-7 is a valid CAS Registry Number.

Paragraph 0056; 0058; 0059; 0061; 0062; 0064-0068, (2019/12/09)
The invention discloses a synthesis method of doxylamine succinate. The method includes: (1) adding 2-pyridylphenylmethylcarbinol into an organic solvent I, adding a catalyst, strong base or alkali metal and 2-dimethylaminochloroethane respectively, performing heating to 100-110DEG C and carrying out reaction for 1-2h; then conducting cooling and filtering; subjecting an aqueous phase to backwashing with the organic solvent I, then performing heating to 70-80DEG C, adding activated carbon for decolorization, then performing filtering, then adding a low-boiling-point organic solvent for extraction, drying the extracted organic phase, and finally conducting reduced pressure concentration at 50-60DEG C to dryness to obtain doxylamine; and (2) dissolving the doxylamine in an organic solvent II, adding succinic acid at 50-60DEG C for reaction, then employing medicinal activated carbon for decolorization and filtering, conducting cooling to a temperature at or below 5DEG C, carrying out stirring crystallization, then performing pumping filtering, and conducting washing with the precooled organic solvent II, and finally performing vacuum drying to obtain the doxylamine succinate. The synthesis method provided by the invention simplifies operation, lowers energy consumption, and has high reaction conversion rate and high yield.
