1-Methoxy-2-propyl acetate
Based on 1 Customer Validation
1-Methoxy-2-propyl acetate is a volatile ester compound found in chocolate made from fermented cocoa beans. 1-Methoxy-2-propyl acetate serves as a hydrolysis substrate for esterases in blood, liver, lung, and nasal mucosa, and is rapidly hydrolyzed to propylene glycol monomethyl ether and acetic acid. 1-Methoxy-2-propyl acetate is proposed as a candidate urinary biomarker for dairy product intake. 1-Methoxy-2-propyl acetate can serve as a solvent and is applied in the electronic-grade semiconductor industry. 1-Methoxy-2-propyl acetate can be used in research related to nephropathy, hepatomegaly, and nasal irritation.

Biological Activity
Description
In Vitro
1-Methoxy-2-propyl acetate (48-120 h) is a fermentation-dependent fruity aroma marker in dark chocolate produced from cocoa beans[2].
1-Methoxy-2-propyl acetate undergoes in vitro hydrolysis to form PM in rat and human blood and liver homogenates, with a half-life of 14-36 min[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
1-Methoxy-2-propyl acetate (300-3000 ppm; whole-body inhalation; 6 h/day; 9 days over 2 weeks) causes dose-related degeneration of the olfactory nasal epithelium in B6C3F1 mice at all tested concentrations, with minimal other systemic toxicity[4].
1-Methoxy-2-propyl acetate (2880 ppm; whole-body inhalation; single 6 h exposure) is rapidly hydrolyzed to PM in vivo following inhalation exposure, and most of the absorbed substance undergoes metabolic transformation rather than being excreted in its parent form[5].
1-Methoxy-2-propyl acetate (1150 mg/kg; oral gavage; single dose) is rapidly and almost completely hydrolyzed to PM after oral administration in rats[5].
1-Methoxy-2-propyl acetate (14.7-147 mg/kg; intravenous injection; single infusion) has an extremely short half-life in rats and is rapidly converted to PM after intravenous administration[5].
1-Methoxy-2-propyl acetate (100-1000 mg/kg; transdermal; single dose; 6-hour occlusive exposure) is absorbed through rat skin, exhibits low percutaneous penetration, and is systemically converted to PM, with no local skin hydrolysis detected[5].

Animal Model:Fischer 344 rats (male and female; 6 to 8 weeks of age)[4]
-
Dosage:300 ppm; 1000 ppm; 3000 ppm
-
Administration:whole-body inhalation; 6 hr/day; 9 days over 2 weeks
-
Result:Caused no unscheduled deaths and no unusual clinical observations at all tested concentrations.
Produced no significant difference in body weights compared to controls at all tested concentrations.
Increased mean relative liver weight of female rats to 3.79 g/100 g body weight at 3000 ppm, compared to 3.59 g/100 g body weight in controls, with no associated gross or histopathologic liver changes.
Slightly lowered mean urinary specific gravity in the 3000 ppm group compared to controls.
Induced slightly reticulated kidneys in all male rats and 2 of 5 female rats at 3000 ppm; histologically, caused slight increased eosinophilic granularity of proximal convoluted tubules in all 5 male rats at 3000 ppm and in 1 of 5 male rats at 1000 ppm.
Caused slight-to-moderate degeneration of the olfactory epithelium in the nasal cavities in 3 of 5 males and 1 of 5 females at 3000 ppm; ciliated respiratory epithelium, trachea, and lungs were unaffected.

Showed no adverse changes in hematology and clinical chemistry analyses at all tested concentrations.
Caused dose-related degeneration of the olfactory epithelium in all male and female mice in the 300, 1000, and 3000 ppm groups, with greater severity and extent at 3000 ppm; slight changes were present in the dorsomedial aspects of the ethmoid recess and anterior olfactory epithelium even at 300 ppm.
Induced focal areas of respiratory metaplasia of the olfactory epithelium in most animals at 1000 and 3000 ppm, and in 1 of 5 female mice at 300 ppm.
Produced acute inflammatory exudate in the nasal cavity lumen in some animals at the 1000 and 3000 ppm concentrations, with inflammation not being a prominent feature of the lesions.
