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.

General description
4-Aminothiophenol (p-aminothiophenol, PATP) is an aromatic thiol. The self-assembly of silver and gold nano particles which are interconnected with 4-ATP to form metal-molecule-metal sandwich architecture has been characterized by surface enhanced Raman scattering (SERS) using an off-surface plasmon resonance condition. Chemical transformation of PATP to 4,4-dimercaptoazobenzene (DMAB) has been extensively studied.
Application
It may be used in the following studies:
- As a water insoluble ligand in the synthesis of pectin–4-aminothiophenol conjugates.
- To functionalize gold nanorods (GNR) in the development of GNR nitrite sensor.
- To form self-assembled monolayers (SAMs) of 4-aminothiophenol in the development of DNA biosensor.
- As a linker to thiol (SH) functionalize multiwalled carbon nanotubes (MWCNTs).
- To generate amino terminated self-assembly monolayers(SAMs) on platinum electrode which forms the base for attachment of single-wall carbon nano tubes (SWCTs).

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