Application

Phenylglyoxylic acid can be used as a precursor in the synthesis of:
  • O-acyl acetanilides by decarboxylative o-acylation of acetanilides using Pd catalyst.[1]
  • Phenylhydroxycarbene by high-vacuum flash pyrolysis.[2]
  • 2-arylbenzothiazoles by reacting with o-aminothiophenol using ammonium niobium oxalate (ANO) as a catalyst.[3]
  • 3-aryl-2H-benzo[b][1,4]benzoxazin-2-ones by treating with o-aminophenol in the presence of ammonium niobium oxalate catalyst.[3]
  • 2-aryl benzothiazoles through potassium persulfate (K2S2O8)-mediated oxidative condensation of benzothiazoles.[4]

Associations between occupational styrene exposure and impairment of hearing function were investigated, guided by three questions: are there hearing losses concerning high frequency and standard audiometric test? Are there dose-response relationships and measurable thresholds of effects? Are there signs of

Questions

1–2 of 2 Questions  
  1. 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.

  2. 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
