Interactions
MIXING TETRAMETHYLUREA WITH MINERAL OIL INCREASED MATERNAL TMU TOXICITY WHEN APPLIED TO SKIN OF RATS.
TETRAMETHYL UREA WAS CAPABLE OF ENHANCING THE TOXICITY OF MORPHINE AND CHLORPROMAZINE IN DOGS, MONKEYS, AND MICE.
TETRAMETHYLUREA LOWERED YIELDS AND/OR INCIDENCES OF TUMORS PROMOTED BY RETINYL ACETATE OR CROTON OIL AFTER INITIATION BY 7,12-DIMETHYLBENZ(A)ANTHRACENE. TOPICAL APPLICATION OF INDUCERS MIGHT HAVE THERAPEUTIC POTENTIAL IN EPIDERMAL CARCINOMA.
Adverse EffectsNeurotoxin - Other CNS neurotoxin
Non-Human Toxicity Excerpts
ONE SC INJECTION OF 5.6 OR 8.6 MMOL TETRAMETHYLUREA/KG OR REPEATED DAILY ADMIN OF 0.9 AND 1.7 MMOL/KG TO PREGNANT MICE HAD A TERATOGENIC EFFECT ON EMBRYOS. GREATEST EFFECT WAS BY SINGLE DOSES ON 8TH OR 11TH DAY OF GESTATION. WHEN GIVEN ON 8TH DAY IT PRODUCED MOSTLY CRANIAL EFFECTS & ON 22ND DAY PAW MALFORMATIONS.
TETRAMETHYLUREA WAS APPLIED TO SKIN OF RATS & RABBITS DURING ORGANOGENESIS. SLIGHT TERATOGENIC EFFECTS WERE DEMONSTRATED.
TETRAMETHYLUREA 150 MG/KG IV ACUTELY OR DAILY FOR 5 DAYS WAS NOT LETHAL & CAUSED ONLY WEIGHT LOSS IN DOGS, MONKEYS, & MICE. DOSES HIGHER THAN 100 MG/KG CAUSED HYPOTENSION IN DOGS.

응용 분야
용도Tetramethylurea is used as a solvent in dyestuff industries, in condensation reaction and intermediates in surfactant. It is utilized for base catalyzed isomerization and alkylation hydrocyanation due to its low permittivity. It reacts with oxalyl chloride to prepare tetramethyl chloroformamidinium chloride, which is used for the conversion of carboxylic acids and dialkyl phosphates to anhydrides and pyrophosphates respectively.
제조 방법
The reaction of dimethylamine with phosgene in the presence of e. g. 50 % sodium hydroxide solution and subsequent extraction with 1,2-dichloroethane yields tetramethylurea in 95% yield.
