3648-21-3 Usage
Chemical Properties
clear light yellow liquid
Uses
Different sources of media describe the Uses of 3648-21-3 differently. You can refer to the following data:
1. Di-n-heptyl Phthalate is a Phthalate derivative and an organic extract contaminant found in drinking water, which was shown to activate Nrf-2-Mediated Antioxidant response in human cell line.
2. Diheptyl phthalate may be used as an analytical reference standard for the determination of the analyte in water samples by magnetic solid-phase extraction based on magnetic multi-walled carbon nanotubes followed by gas chromatography-tandem mass spectrometry (GC-MS/MS) and in food samples by liquid chromatography-tandem mass spectrometry (LC-MS/MS).
Definition
ChEBI: The diheptyl ester of benzene-1,2-dicarboxylic acid.
General Description
Odorless white liquid. May float or sink in water.
Reactivity Profile
DI-N-HEPTYL PHTHALATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Can generate electrostatic charges. [Handling Chemicals Safely 1980. p. 250].
Health Hazard
Inhalation of vapors from very hot material may cause headache, drowsiness, and convulsions. Contact with eyes may cause irritation.
Chemical Reactivity
Reactivity with Water No reaction; Reactivity with Common Materials: May attack some form of plastics; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Check Digit Verification of cas no
The CAS Registry Mumber 3648-21-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,4 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3648-21:
(6*3)+(5*6)+(4*4)+(3*8)+(2*2)+(1*1)=93
93 % 10 = 3
So 3648-21-3 is a valid CAS Registry Number.
