【Specification】

? Tetramethyl ammonium chloride , with CAS number of 75-57-0, can be called methanaminium, N,N,N-trimethyl-, chloride (1:1) ; N,N,N-Trimethylmethanaminium chloride ; TMAC . It is a?white crystal. Tetramethyl ammonium chloride (CAS NO.75-57-0) is used as a phase transfer catalyst for anionic reactants. In small concentrations, also has been shown to enhance yield 5-10 fold at 3M by stabilizing the AT base pairs. Besidea used with polymerase chain reactions to increase yield and specificity.

【Report】

Reported in EPA TSCA Inventory.

Biomedical Effects and Toxicity

【Pharmacological Action】
- Agents that mimic neural transmission by stimulation of the nicotinic receptors on postganglionic autonomic neurons. Drugs that indirectly augment ganglionic transmission by increasing the release or slowing the breakdown of acetylcholine or by non-nicotinic effects on postganglionic neurons are not included here nor are the nonspecific cholinergic agonists.
