Hi, Hope this email finds you well. I have been wondering if you could provide me with a price estimate for L-phenylalanine CAS 63-91-2? We are looking for a competitive price and the quantity we are looking for (initially) is 200 kg. With best wishes, Paulina Dubiel (she/her) Senior Scientist
Dear ECHEMI sales representative, My name is Frances Nicolas, and I am a Ph.D. researcher from the Laboratory of Biosciences and Bioengineering for Health at the French Alternative Energies and Atomic Energy Commission (CEA). Our research involves the developing new mass spectrometry-based methods for protein identification and quantification that are more sensitive and specific than traditional methods. For this purpose, we decided to try some new protocols, which involves the use of some specific reagents, which your company might be able to provide. I am reaching out to you to inquire about the pricing, availability, and the fractionation amounts of the following reagent: Name: Paramyon / Paramion. IUPAC name: trimethyl-[4-[4-[4-(trimethylazaniumyl)phenyl]hexan-3-yl]phenyl]azanium;diiodide CAS: 604-92-2 / PubChem CID: 11792 In addition, we would be interested in similar reagents that shares part of their structure: Two or more positive charges given by quaternary ammonium salts, attached to an aromatic body. Example of this would be a derivate from the extra methylated leucomalachite green (CAS: 129-73-7 / PubChem CID: 67215). What we are not looking for is compounds with contains other functional groups besides the tetra-substituted nitrogen. This is not: primary, secondary, or tertiary amines; sulfates; carboxylates; phosphates, alcohol groups, etc. We are indifferent to the iodine contra-ion; it could be bromine or chloride as well. We appreciate your prompt attention to this. If you have any questions or require further clarification, please do not hesitate to contact me at this email. Thank you for considering our inquiry, we would be glad to work with your esteemed company. Best Regards, Frances Nicolas.
