Transportation condition Domestic: We use cold chain in summer. But in winter, it is ok to transport directly with a few ice bags. But it has strict storage condition. Overseas: Cold chain transportation（-18℃～-22℃） Recommend shipping method by air＞by land＞by sea We usually quote for you FOB. If you need CIF quotation, we will try to find cheaper one. Tell us if you have your own freight forwarder. Storage condition: Inert atmosphere,Store in freezer, under -20°C Shelf life: 6 months to one year Minimum Order Qty： 10gm(negotiation) Certification: COA, HPLC, GC, HNMR, Assay, Water Content(K.F), TLC available We usually have HPLC, AT, TLC. If you really want us to test HNMR, note please.Einecs 237-026-9; benzyl (1,2,3,4-tetrahydro-2,5-dioxo-1,3-oxazol-4-yl)acetate; 2-[(4S)-2,5-Dioxooxazolidine-4-yl]acetic acid benzyl ester; a-Benzyl-L-aspartic acid N-carboxyanhydride; (4S)-2,5-Dioxooxazolidine-4-acetic acid benzyl ester; (4S)-4-(Benzyloxycarbonylmethyl)oxazolidine-2,5-dione; (4S)-4-[2-(Benzyloxy)-2-oxoethyl]oxazolidine-2,5-dione; 3-(Benzyloxycarbonyl)-N-carboxy-L-alanine anhydride; (S)-2,5-Dioxo-4-oxazolidineacetic acid phenylmethyl ester; H-ASP(OBZL)-NCA; L-aspartic acid 4-benzyl ester N-carboxyanhydride;They are used to pack a small amount of products. (1g to 10kg). And then put them in the hard cardboard boxes.The first one is often used to pack a small amount of products. The second one is used to pack larger ones. (15kg to 25kg). And we will label on the straight ahead. And stick the warehouse receipt on the lid.Poly amino acids (polypeptide) materials have excellent biocompatibility, biological activity and degradability. They have been widely used in drugs and gene delivery, tissue engineering, polypeptides, and antibacterial areas. In the past centuries, scholars in many international polymer areas have been explored and optimized NCA aggregation; amidamine has caused NCA aggregation to be the most widely used way to this day. However, this NCA aggregation method is slow (usually it takes 2-3 days to complete), and it is difficult to prepare a large molecular measurement polypeptide; at the same time, due to the poor stability of the NCA monomer, long-term reactions may lead to side reactions. produce. The more prominent disadvantage is that the NCA aggregation is highly sensitive to water. The aggregation reaction is generally performed under the protection of inert gas in the glove box, which limits the application of parallel polypeptide molecular libraries and large -scale synthesis. The core problems and challenges that these NCA aggregates have not been solved have hindered the further development of this field and the application of polypeptides in many fields.
