4991-30-4 Usage
Common Uses
Plasticizer in polymers and resins
Solvent
Additive in personal care products
Formation
Result of the reaction between 1,1-ethanediol (ethylene glycol) and benzoic acid
Physical Properties
Improves flexibility of plastic and rubber materials
Enhances durability
Increases softness
Health Risks
Potential skin and eye irritation
Should be handled with care in a controlled environment
Chemical Structure
Derived from the esterification of 1,1-ethanediol with benzoic acid, resulting in a molecule with two benzoate groups
Appearance
Typically a colorless to pale yellow liquid
Boiling Point
High (specific value depends on the source and purity)
Density
Higher than water (specific value depends on the source and purity)
Solubility
Soluble in most organic solvents, such as ethanol, acetone, and diethyl ether
Stability
Generally stable under normal conditions, but may decompose upon exposure to heat, light, or strong oxidizing agents
Environmental Impact
Potentially harmful to aquatic life and should be handled and disposed of properly
Regulatory Status
May be subject to specific regulations and restrictions depending on the region and intended use.
Check Digit Verification of cas no
The CAS Registry Mumber 4991-30-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4991-30:
(6*4)+(5*9)+(4*9)+(3*1)+(2*3)+(1*0)=114
114 % 10 = 4
So 4991-30-4 is a valid CAS Registry Number.

Synthesis and structure of highly polarised double-bond compounds derived from S-proline
Aitken,Ali,De Elena,Lightfoot
, p. 7965 - 7968 (2000)
Reaction of the chiral iminium salt 3 with stabilised carbanions gives the compounds 4-9 containing a highly polarised double bond. The extent of this polarisation is determined by variable temperature 1H NMR studies, comparison of 13C NMR chemical shifts and an X-ray structure determination. (C) 2000 Elsevier Science Ltd.
