Descrizione generale

The kinetics and mechanism of the gas-phase thermal decomposition of 2-methyl-1,3-dioxolane has been studied in a static system[1]. The infrared spectra of solid, liquid and gaseous 2-methyl-1,3-dioxolane has been studied[2]. Low-temperature ozonation of 2-methyl-1,3-dioxolane in acetone-d6, methyl acetate and tert-butyl methyl ether has been reported[3].

Some compounds that inhibit acetylcholinesterase (AChE) activity compete directly with quinuclidinyl benzilate (QNB) binding, a muscarinic antagonist which binds to all subtypes equally, and with cis-methyldioxolane (CD), an agonist that binds with high affinity to the M2 subtype of muscarinic

To study the role of central cholinergic mechanisms in hypertension, we have determined nicotinic and muscarinic agonist binding sites in the brain regions of stroke-prone spontaneously hypertensive rats (SHRSP), using [3H]nicotine and [3H]cismethyldioxolane (CD). There was a significant decrease in

1. Muscarinic receptors mediating contraction of rabbit endothelium-denuded aorta have been characterized functionally, in vitro, using a range of antagonists (atropine, pirenzepine, methoctramine, himbacine, 4-diphenyl-acetoxy-N-methyl piperidine methiodide (4-DAMP) and para-fluoro-hexahydro-siladifenidol (p-F-HHSiD). 2. The non-selective muscarinic agonist, (+)cis-dioxolane, induced concentration-dependent contractions

Low-temperature ozonation (-78 degrees C) of 2-methyl-1,3-dioxolane (1a) in acetone-d6, methyl acetate, and tert-butyl methyl ether produced both the corresponding acetal hydrotrioxide (3a, ROOOH) and the hemiortho ester (2a, ROH) in molar ratio 1:5. Both intermediates were fully characterized by

The radioreceptor assay for acetylcholine (ACh) is based on the ability of the ACh to compete with the specific binding of [3H] cis-methyldioxolane to muscarinic receptors of rat cerebral cortex membranes. The technique described was used to measure ACh levels

Questions

1–2 of 2 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
