Description

Product Detail

White crystalline powder, odorless, with a strong sweet taste that is pure and about 100 to 200 times sweeter than sucrose. Melting point is 235°C (decomposes). It has general properties of amino acids. Stable under dry conditions or at a pH of 2–5, but can hydrolyze into single amino acids in strongly acidic solutions, and can cyclize into diketopiperazine under neutral or alkaline conditions. Its solubility in water (25°C) depends on pH: 10.2% at pH 7.0 and 18.2% at pH 3.72. Isoelectric point

Item	Value	Condition / Remark
Items	Specifications
Appearance	White crystalline powder, odourless, intensely sweet with a slight cooling sensation	Room temperature
Sweetness	About 100–200 times that of sucrose (most sources use 180–200)	%~0.007 % Equal-sweetness weight ratio; sweetness threshold 0.001–0.007 %
Melting point	About 246.5 ℃ (with decomposition); other sources give 235 ℃ (decomposition) or 242–248 ℃; a "double melting point of about 190 ℃ and 245 ℃" is also reported	Decomposes on heating; no well-defined melting point at atmospheric pressure
Boiling point	None (decomposition precedes boiling)	Atmospheric pressure
Density	1.347 g/cm³ 1.347 g/cm³	25 ℃; true density
Solubility in water (25 ℃)	Slightly soluble; about 10.20 % at pH 7.0 and about 18.2 % at pH 3.72	Solubility increases as pH falls
Solubility in organic solvents	Methanol about 3.72 %; ethanol about 0.26 %; readily soluble in formic acid and dimethyl sulfoxide; practically insoluble in n-hexane and dichloromethane	25 ℃ 25 ℃

Isoelectric point	pH approx. 5.2	25 ℃; near the solubility minimum
LogP (octanol/water)	approx. 0.542 (estimated)	—
Stability	Stable when dry or at pH 2–5; hydrolyses to the free amino acids in strongly acidic aqueous solution; cyclises to diketopiperazine (DKP) under neutral or alkaline conditions; decomposes and loses sweetness above 80 ℃	Reactions accelerate with temperature; unstable in aqueous solution
Hygroscopicity	Low (stable under dry conditions)	Protect from moisture in high-humidity environments

ECHEMI Editorial Reference

Aspartame is an artificial, non-saccharide sweetener used as a sugar substitute in some foods and beverages.Target: OthersAspartame is a flavoring agent sweeter than sugar. Aspartame is a methyl ester of a dipeptide used as a synthetic nonnutritive sweetener. Epidemiological studies on aspartame include several case-control studies and one well-conducted prospective epidemiological study with a large cohort, in which the consumption of aspartame was measured. The studies provide no evide
White, odourless, crystalline powder having a sweet taste. Approximately 200 times as sweet as sucrose|Solid
Aspartame is a dipeptide obtained by formal condensation of the alpha-carboxy group of L-aspartic acid with the amino group of methyl L-phenylalaninate. Commonly used as an artificial sweetener. It has a role as a sweetening agent, a nutraceutical, a micronutrient, a xenobiotic, an environmental contaminant, an apoptosis inhibitor and an EC 3.1.3.1 (alkaline phosphatase) inhibitor. It is a dipeptide, a carboxylic acid and a methyl ester. It derives from a L-aspartic acid and a methyl L-phenylalaninate.|Flavoring agent sweeter than sugar, metabolized as phenylalanine and aspartic acid.|Flavoring agent sweeter than sugar, metabolized as PHENYLALANINE and ASPARTIC ACID.
