Different sources of media describe the Uses of 4584-49-0 differently. You can refer to the following data:
1. 2-Chloro-N,N-dimethylpropylamine hydrochloride (DMIC) is used as intermediate for the syntheses of pharmaceuticals (e.g. isothipendyl, methadone and promethazine)
2. Hydrochloride salt of 2-Dimethylaminoisopropyl Chloride, used in the synthesis of analogues of lipophilic chalcones, which act as antitubercular agents.
General Description
Off-white chunky solid.
Air & Water Reactions
2-Dimethylaminoisopropyl chloride hydrochloride is hygroscopic. Soluble in water.
Reactivity Profile
2-Dimethylaminoisopropyl chloride hydrochloride is incompatible with strong oxidizing agents. . Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
Fire Hazard
Flash point data for 2-Dimethylaminoisopropyl chloride hydrochloride are not available; however, 2-Dimethylaminoisopropyl chloride hydrochloride is probably combustible.
Synthesis
Following the procedure of Schultz and Sprague, J. Am. Chem. Soc., 70, 48 (1948), a solution containing 3.77 g. of 1-dimethylamino-2-propanol and 10 ml. of chloroform was cooled with stirring to a temperature of about 0° C. A solution of 5.72 g. of freshly distilled thionylchloride in 2 ml. of chloroform was added thereto. The reaction mixture was allowed to come to ambient temperature over a period of about 30 minutes and was then heated to refluxing temperature for an additional 30 minutes. The precipitated material redissolved on heating. 1-Dimethylamino-2-chloropropane hydrochloride began to crystallize from the boiling solvent. The reaction mixture was cooled, diluted with ether and filtered. The reaction product comprising 1-dimethylamino-2-chloropropane hydrochloride weighed about 5.5 g. (95 percent yield). Recrystallization yielded purified 1-dimethylamino-2-chloropropane hydrochloride melting at 192°-194° C.
Check Digit Verification of cas no
The CAS Registry Mumber 4584-49-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,8 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4584-49:
(6*4)+(5*5)+(4*8)+(3*4)+(2*4)+(1*9)=110
110 % 10 = 0
So 4584-49-0 is a valid CAS Registry Number.

The systemic investigation of the structural impacts of side chains on the pH- and thermo-responsiveness of tertiary amine functionalized poly(l-glutamate)s (TA-PGs) was carried out. The TA-PGs polymers were effectively synthesized by Cu(I)-catalyzed azide-alkyne cycloaddition click reaction of azido tertiary amines with poly(γ-propargyl-l-glutamate) (PPLG). Turbimetric measurements were performed to characterize the pH- and temperature-induced phase transition of TA-PGs in aqueous solution, which suggested a structural dependence of the properties on the N-substituted groups and the "linkers" between 1,2,3-triazole ring and the tertiary amine groups in the side chains. In detail, the pH responsive properties of TA-PGs were basically determined by the hydrophobicity of the N-substituted groups in the side chains and the pH transition point (pHt) decreased as the increasing hydrophobicity of the N-substituted groups, while the temperature-responsiveness of TA-PGs were affected by either the N-substituted groups or the "linkers." TA-PGs with a moderate N-substituted amine group (e.g., DEA, PR, and PD) or a branched "linker" (e.g., iso-propylene and 2-methylpropylene group) were more likely to express the LCST-type phase transition tuned by pH variation. These structure-property relationships revealed in this study would help to develop the applications of TA-PGs in smart drug delivery systems. Copyright

The 2-chloro-1-dialkylamino-propanes 4a-d are reacted with diphenylacetonitrile under phase transfer conditions to give a mixture of the nitriles la-d and 2a-d. Both chloro-dialkylamino-1-phenyl-ethanes 7a-d and 8a-d lead to 4-dialkylamino-2,2,3-triphenyl-butyronitriles 6a-d.
