Documented Uses

• Used in solvents and as an organic intermediate; [HSDB]
• 2-Isopropylnaphthalene is contained in solvents and used as a chemical intermediate.
• ... Produced by alkylation of naphthalene with propylene.
• Naphthalene, 2-(1-methylethyl)-: ACTIVE
• Pulmonary toxicity of 2-isopropylnaphthalene (2-IPN) and its photoproducts was studied in mice. Twenty-four hours after the intraperitoneal injection of 2-IPN or its photoproducts, 2-isopropenylnaphthalene (2-IPeN) (1000 mg/kg), 2-acetonaphthone (2-AN) (700 mg/kg), beta-naphthol (BN) (50 mg/kg), phthalide (PH) (500 mg/kg) and phthalic acid (PA) (100 mg/kg) produced pulmonary damage, but 2-IPN (3000 mg/kg) and 2-(2-naphthyl)-2-propanol (2-NP) (100 mg/kg) did not produce pulmonary damage. The maximum levels of 2-IPN
• Over 95% of orally admin 2-isopropylnaphthalene was absorbed within 24 hr from the GI tract in rats. Peak levels in the blood, liver, kidneys, brain, heart, spleen, and muscle were observed at 2 hr, whereas peak levels in the adipose tissue and skin were observed at 4-6 hr. Amount of unchanged 2-isopropylnaphthalene in urine was small. In rats fed the experimental diet containing 0.1% for 14 or 28 days, 2-isopropylnaphthalene in the adipose tissue decreased to 1/3 within 24 hr after halting continuous ingestion.
